Vala generates a robust C/GObject API from the Vala code, the only
dependency is for developers who want to recompile the C code from the
Vala code. I'm not saying it should be done in Vala over C (I'm
thinking it) but it's important to note that Vala compiles to pure
C/GObject. In any case, we could mix C and Vala quite easily, using
both at the same time, or one or the other for specific things, or
starting in Vala then changing to C in the end, without changing the
GObject C API.

I agree, but just to be clear, that's what's been goin on with
Geany-DBus/Geany-Vala-Binding (picturing how the interface *should*
look). That's not say we don't need to think about it A LOT more, but
at least we have some ideas started with those projects.

If I'm not mistaken, with GObject-introspection, the GTK-DOC gets
wrapped up in the target bindings, so at a bare minimum, there would be
docs for things like methods, properties, signals, etc. Of course I'm
just assuming the GTK-DOC gets put into the target bindings, I've never
actually tried to do it, and as always, the C API needs good docs :)
