Adding new functions in Lightroom too slow in my opinion.

I need smooth zooming but Lightroom know better and imposes his own way on me. 

Infinate zooms would require infinate library previews.

So, we have incrimental zooms. 

This is not the forum for feature requests, as Adobe doesn't monitor this forum for feature requests. On the main page of the forum is a linke that says "Submit Product Feedback", use that link to put forth your request.

Maybe because people wanted a local hue slider?

But you are in the wrong forum here, we are just Lightroom Classic users, we don't know why Adobe does things, and we also can't make changes to the program and we can't cause them to speed up. You need to direct your concerns to Adobe and not to us Lightroom Classic users. On the main page of this forum is a link that says "Submit Product Feedback", use that link.
