note, that it's not the talking JSON part that's difficult to do in C (it's
just midly annoying compare to a highlevel language), but all the other part of
a toolstack. Since there's no performance requirements, writing in C is just a
bit of a waste ot time, but that's up to the developpers to choose the tools he
wants, even if it's not the most appropriate one ;)

if you're talking about the QMP interface then I agree with you. This need to
be back/forward compatible as much as possible and stable.
the other interface (i.e. the user monitor) has no business beeing
backward-compatible though, since it should never be used to talk a RPC.
