[Standards] Deprecating Privacy Lists

I agree to Florian, Goffi etc...

XEP-0016 is complex, but powerful. I see no reason to deprecate it, just because there's a similar XEP (0191). In our company we've had an requirement to be invisible to certain roster groups. This is not solvable with other XEPs.

The other mentioned use case -blocking users, which are not subscribed to my presence- is perfectly valid, too.

I don't care about Prosody, but why would one remove XEP-0016 entirely? It will break clients only.

I'm strongly against deprecating XEP-0016: we are working a lot with groups,
and neither XEP-0191 nor XEP-0186 allow to block/be (in)visible only for a

I think a XEP should not be deprecated if its features are not superseeded by
the new one(s).
