Annex E remains in the proposed Ada 202x standard.

Compiler support, of course, is up to vendors. Dunno if anyone is still 
supporting it.

That was the promise, not sure it ever really was realized. Since the Annex 
was weakened enough that third-party support isn't really possible anymore 
(necessary to allow it to be used with current middleware), it's really a 
vendor-specific thing these days.
