I had a bit of chat with ofono guys. They told me that ofono does
indeed have GPS "API" but its raw NMEA sentences fed through some fds
rather than directly on the D-Bus interface.

I think I'll add an ofono backend soon and would hope that that is all
I need (apart from missing API you mentioned) to do to make geoclue2
work for your platform. :)
