Given that libcapsule is very glibc- and ELF-specific, doesn't work
properly without new glibc feature work that isn't in Debian yet (I've
lost track of whether/when it got merged upstream, it might be in 2.34)
and wasn't written by me, the answer is likely to be no.
As far as I understand it, the PE loader used for Wine is part of Wine,
so it has total control over the libraries that it loads and how it loads
them. This means that if Wine developers (the experts on this codebase)
have decided a libcapsule-like approach isn't feasible or isn't desirable,
they are probably right.
More generally, if Wine developers wanted Wine's dependency libraries
to be in one version of reality, and Windows DLLs to be in a different
version of reality, then there's a straightforward way to do that:
use ELF .so dependency libraries, like older versions of Wine did, and
don't give them a representation in the PE layer. Presumably they have
put in the work to move from ELF to PE dependency libraries because it
has some compelling advantage, rather than creating work for themselves
for no reason!
