Maybe it could, but I don't see the point.
Eli has written the code for w32 notifications which are less fancy than
the DBus ones,
but which have the benefit of being w32 native.

From what I remember in this area, what I would favor (if possible) is :
- disable DBus for w64 (and w32 ?) because it does not work, even if it
compiles without complaining
- at the elisp level, use the native w32 notifications whereever possible
when DBus notifications are requested.

Oh, I didn't even notice that IM could be using DBus notifications.
Actually, the msys2/mingw64 version does not depend on DBus :
