By definition an application that works fine on Windows should work fine
on Wine. If they don't, it's a bug.

Sounds like a bug to me. Refcounting differences can cause crashes and
memory leaks.

I'd be very surprised if there were no apps that depended on it, actually.
Given the number of crashes we've seen caused by refcount problems in
this part of the code, I'd say there definitely are.
