interested in it. (about the only way is to send out a presence probe
to everyone on your roster. Horrible.)
I always figured that as soon as you change the privacy lists to unblock
presence, then the server should immediately deliver the latest presence of
the unblocked jids. But maybe privacy lists aren't meant to be that smart.
I personally don't think brainless on/off stanza filtering is all that useful.
For the filtering use-cases people actually want, such as
invisible/visible/away-to/etc lists, and various optimized deliveries over
mobile, we need the server to be smarter.

This isn't stated explicitly in the privacy lists XEP, but it makes
perfect sense. The feature wouldn't be quite that useful without it,
would it?
But privacy lists (in my opinion) can't cope with some real-world
problems and needs nowadays. That's why I think it should be redone from
scratch and with everyone's concerns in consideration. I don't think
there are usable client-side implementations anyway.
I will have some time, so I may try writing something if more people
agree with me.
