Nope, doing this (partially) outside of the company I work with, I'am using
GPL license for this.

The same answer as with gcc or any other tool: Users of msvc will be most
likely offer (limited) support for it.
It seems to be natural that FOSS devs and/oir users are asked from time to
time with "what about support" question. Hint: there are companies or other
organizations that having software commodized by pushing FOSS, are happy to
provide support instead fo pushing paid updates. It's an ecosystem that, we
can hope, will evolve for win32 target too.

All can vary from app to app. Quite similar question to "how to ensure app XYZ
is well packaged in all Linux distros" - nobody can ensure this. Also similar
question to "how to ensure Qt-only app is maintained on win32. Let's note
again, we're not mirroring KDE desktop (in term of set of apps) on win32, but

If the application if LGPL-ed, it's OK. If it's GPL-ed, it's needed to receive
written permission (called GPL exception for building using non-GPL tool) from
Example: KBabel in 2004:
