I'm thinking most potential uses of the binary API, other than C
programmers, would be happier with a D-Bus version generated from
those same *.hx files.  Because then it's easy to call the API from
Python, Perl, even shell, etc.  Whereas libqemu.so would be relatively
difficult to use from those languages.

(Aside: I don't particularly like D-Bus.  But it does seem to work
for this sort of thing.)
