For general compatibility, XEP-0126 is best - unlike XEP-0018 it
doesn't mess with core XMPP. From a high level it's also far from
ideal though. While privacy lists are already implemented in many
clients and servers, it makes for one ugly and complicated way to say
"Hey, I just want to be online without people seeing me!".
My eggs are in XEP-0186's basket. It would take an hour at most to add
support for it to Prosody, and it's likely as trivial for other
servers too. It also couldn't get any easier from the client's
The main problem is that this isn't moving - most people, XMPP
developers at any rate, seem comfortable /enough/ with the current
situation to not be rushing to implement this.
Therefore if any client has or is implementing XEP-0186 support and
wants to test it against Prosody then feel free to poke me off-list.

You can get the list of lists:
