I have no problems with the icon sizes. This is the first post I have ever seen on this problem, but if you can get a lobby going with enough folks filing a feature request then maybe something will happen. Feature changes are democratic for the most part.
BTW, Adobe is working hard to support Windows HR displays. Most apps are already optimized for Apple HR displays - because Apple was the first to introduce them and make them available to the public. Give Windows HR display support a while to catch up.
