We can see endless questions about Dropbox vs TortoiseSVN vs many other apps icon overlays conflicts.
Two examples:
Why are Icon Overlays (from 3rdParty-Apps) not showing up in the Win8 Explorer?
Can I prevent the change of overlay icons?
In my case, I only have Dropbox and TortoiseSVN. Dropbox is really becoming annoying – after every update, I need to run a script I made that deletes Dropbox's overlays from registry and then restarts Windows Explorer.
I understand that Windows limits overlays to 15 probably because of performance.
However, would increasing to 25~35 cause a huge performance impact?
Why hasn't Microsoft realized yet that this is a very popular issue and tried to make a fix for this?
Why isn't there, at least, an option that advanced users can change to increase this limit?

Remove any unused overlays from the following location:

Since the current limit cannot be changed its not possible for us to predict what sort of performance impact there would be if the limit was increased.
I would presume it effects less people then you think it does. Only somebody, from the Windows Shell team, would actually know this answer. Until Microsoft makes their decision decision known, we can only make educated guesses, which basically would be that nobody has increased the limit.
