Yes, I'm confident that we'll be able to maintain compatibility with
activities that use the current API, although I also hope that we'll
come up with something much better soon.

Well, the low level API isn't really that hard to use. The dbus-python
bindings already do a great work of making easier to use DBus services
from python. If you find any capability in the low level bindings that
could be useful to activities and is not yet in the python wrapper,
