I always assumed the intent of XEP-0191 was to make the subject appear
offline to any blocked contacts, and make any blocked contacts appear
offline, for the duration of the block.
So as I recall - and no doubt Edwin and Kev can say if I recall correctly -
when I last implemented it from scratch, I had the server probe a contact
when unblocked, and and otherwise make it appear as if both sides had just
come online (or stayed offline, or whatever).
But you're quite right, none of this is in the letter of the specification
(even the intent).
