Adding to this C wrappers for QMP commands threatens to make QMP command
arguments part of the library ABI. Compatible QMP evolution (like
adding an optional argument) turns into a libqmp soname bump.
Counter-productive. How do you plan to avoid that?
You could make the API use QObjects; then you're completely isolated
from high level protocol changes. Of course, this is less useful than
the full API.
