Not sure if you're referring to the UUID only. If that's the case,
you're right, I haven't changed that since the BlueZ 4 code doesn't do
it either.

In any case, I could integrated it here if you consider this
important: one possible approach would be to add a bool uuids_ready to
struct pa_bluetooth_device, since we have to distinguish the
empty-uuid-list case vs property-not-present.

Regarding "alias" and "trusted", I think they don't do any harm and
some other module might potentially be interested in these fields.
Again, if you want to keep the codebase minimal, we can remove them
trivially.

Besides that, I think the rest of the changes mentioned in this thread
have been incorporated:
- Comment removed instead of updated
- All non-optional properties checked (with the exception of UUID),
and otherwise fail in parse_device_properties()
- D-Bus message signature check
- Style fixes
- Log trace fixed (s/address/object path/)

Cheers,
Mikel
