No, it doesn't. The version upstream does not have all the bells
and whistles the mld-1.8.0 version has, yet. Focus of the latest
mainline commits was on the driver model and the switch to configfs.

The functionalities you're referring to have _not_ intentionally been
dropped. They will find their way into mainline. If there are urgent
feature requests, we could prioritize them.

Bottom line is, the upstream version is the one you should be using,
as it is going to replace the mld-1.x branch. This is exactly what we
will soon be doing for AGL by the way.
