We can provide a generic QMP dispatch interface that high level

They can do that by accessing QMP directly. Why would a Python developer
get in the mess of writing a Python binding for libqemu if they call do
the exactly same thing by using its native json module?
Man, opening a QMP connection from Python and sending commands can be
done with a few lines.
Problem is, without a libqemu, libvirt cannot return a QMPContext that
can be used by python bindings. This is the problem that all high
level languages have with respect to RPC transports.
You need libqemu to deal with establishing the transport. That code
needs to be common and shared across languages.
Dispatch can be handled by the high level language.
We just ought to also provide some simple C wrappers for all of the
functions. Yes, the C interface is inferior to the generic interface
but that's fine.
Why don't we start with my simple lib suggestion and wait one or two
releases to see what happens?
I have no problem starting without the generated C wrappers. But we
need the core library to have the right abstractions with respect to
transports.
