I can’t think of any reasons why not. Perhaps a GDBus automake snippet

could be installed by GLib which:
 1. Installs D-Bus XML interface files.
 2. Includes rules for building documentation and C/H files from them.
 3. Validates the XML interface files for well-formedness.

I think that would be really helpful; note that my goal here would be just to make things more convenient for developers and not to use it as a way to guarantee API stability of a service through auto-generated code.

In that sense, I see your points 1), 3) and the first half of 2) as something typically used by the service, and the second half of 2) as something a consumer would call.

Another thing that to take into consideration is that some projects currently encode the location of the DBus interface xml into their pkgconfig file [1].

Is that something we should recommend? I believe if we had this snippet, the macro could just do a lookup following the usual rules of XDG_DATA_DIRS and we could avoid using pkgconfig, but perhaps I'm missing something.
