The entire 'block messages from strangers' thing is a poor mans workaround
for the spam problem. I don't think there is a use case for this outside of
fighting spam. And it's not even very effective in fighting spam as
spammers could just move over to subscription spam.
I personally couldn't even use it,  because blocking messages from
strangers would it turn mean that I would have to allow presence
subscription for random people on the Internet who want to contact me.

And yes there are a few users out there for which blocking strangers is an
effective way of fighting spam. However so is blocking messages with
Cyrillic letters in them. This doesn't mean we should make a standard for

The spam problem needs to be addressed. But not in this way.
And deprecating privacy lists doesn't mean the current implementations will
go away. So everybody for whom this is a good enough work around for now
can still use it until we come up with something better.
