A couple of things:
Not a huge priority.
RDM list all the different icons. So for a reason, the binaries of two similar icon is not the same.

No, I get that. If the icon is different, uploaded more than once, etc. it should show it as a separate entity. But I take a custom PNG icon, upload it once, and use it for multiple different objects. When I go to choose an icon (not upload, but from the available list) it shows up multiple times... that icond I uploaded only once but used on several objects might show up 2 or 3 times amongst all the other icons. Only happens for icons I upload.
