In article <5F5D3BAE-B38C-4663-800B-3F591899086B@verisign.com> you write:

That makes sense, but it also seems needlessly cruel. I expect
registrars would build ad-hoc lists of who handles EAI and who
doesn't, to provide better reports to their users, which would
then inevitably get out of date.

If we do this it really would be nice if there were a signal for who
handles EAI and who doesn't.
