InDesign and EPS icons changed to AI

If these problems exist. If they worked before then why fix what's not broken. 

I agree if creating new files, stick to a more modern format.

In my eyes, if they supply eps files, or you have used them without issue, then carry on. 

EPS files saved in illustrator do support transparency (I use them all them time with a Barcode creator) - an Illustrator saved EPS file will have transparency - and some eps data. 

We don't even know if this OPs files are in fact even Illustrator files, they could be photoshop EPS files. And we all know that if you open a Photoshop EPS it will completely flatten everything in there. 

So any vector data (text layers, vector shapes, vector masks) would be rasterised. 

Not something you want to force into a file that was working well before. 

Anyway - we can agree to disagree. 

I certainly don't mess with supplied files unless there's an issue with the output. 

And at that point I need to send back to the client to ensure they are happy with the results. 

If I did change the format without the clients knowledge and it went wrong, that's on me. 

If something goes wrong with supplied file (at a point I'm not involved) then I can help them resolve it. 

But it's certainly not up to me to start converting working files to other formats for no reason.
