Hi @lfcorullon, yes it could definitely be easier. But here is some code that works, at least in the basic case. Let me know if it is what you were thinking.

/**

* Split a double facing-page spread into two spreads, preserving sided-ness.

* CAUTION: not tested beyond the basic case!

Hi @lfcorullon ,
in case you need this for adding bleed to the spine I have another suggestion:
[1] Make sure that the pasteboard below and above the pages is at least double the height of the page plus some extra space.
[2] Move one of the pages plus its contents down so that the right edge of the left page does not touch the left edge of the right page in the spread.
Both pages still share the same spread.
To accomplish this without scripting is relatively easy by using the Page tool to select a page and the Transform panel to move the selection.
From my German InDesign, where I checked the option "Move objects with page" from the Control panel.
The page is selected with the Page tool, the Transform panel's Y value is set to 305 mm (page height in my case is 297 mm):
After the transformation there is plenty of space on all sides of the pages to apply bleed:
In case you need to do this for more pages in a document, simply select the Page tool first, then open the Pages panel and cmd select (Ctrl select on Windows) all pages you want to move before using the Transform panel.

Why?
If you are doing it from the UI, it would usually be to add an extended inside bleed for binding methods where the inside edge is trimmed and visible, not folded. Something like Wire-o.

Why not include it in the page size?

The trim and bleed boxes/marks would be wrong in an exported PDF, and crossovers wouldn’t work.
If the inside edge is exposed I would do this:

I'm pretty sure printing shop can handle those special circumstances.
I'm case of crossovers - you need to place the same image twice and shift it anyway - I'm pretty sure it would be much easier / quicker to do it on the same spread - rather then on two different spreads.
Then - can't check it right now - but how will PDF look like? Especially, if client wants to see spreads...
case of crossovers - you need to place the same image twice and shift it anyway
On a straight crossover you can leave the spread as is—no gap for the bleed—in that case the bleed comes from the opposite page and there is no need to split the art. Here the with Facing Pages turned off, the top spread is pulled apart and orange filled rectangle stops at the inside trim. The bottom spread is attached at the spine, and the cyan filled A crosses over (its spread is not pulled apart)
The bleeds are correct in the exported PDF, and the trim is 8"x10"
But if you take pages apart - and move to separate spreads...
This is a non facing page document set up as spreads. With non facing pages you have the option to move the spread pages apart for an extended bleed or leave them connected. You can’t do what I’m showing with a facing page document, and because the spread pages can be pulled apart, there is no need to move the pages to separate spreads:
Yes, I helped @lfcorullon with the code, but I wouldn’t use it.
By @rob day
And that's why I've asked "why" - what is his reason to move pages to separate spreads.
And that's why I've asked "why" - what is his reason to move pages to separate spreads.
If, for some reason, the document was created as Facing Pages, it might be easier to split the pages that need an inside bleed to individual spreads, rather than change a complex existing document to non facing pages.

Right, but then somehow we've drifted away 😉
The trim and bleed boxes/marks would be wrong in an exported PDF
By @rob day
In what way they would be wrong?
They'll be more correct than if you will work on an "usable" part of the page without the space for punch holes.
Unless I'm missing something?
In what way they would be wrong?
If the document’s Width and Height are 8"x10" (the trim), and the bleed is .125", an exported PDF’s trim and bleed box would be this:
If you add an extra .125" to the pages the trim is 8.125" not the desired 8" and you would get this in the PDF:
So if you are doing that there is the risk of miscommunication.
With wire-o the punch holes are inside of the trim.
By @rob day
You mean the area that will be cut off?
