I think this is foolishly short-sighted and it ruins the simplification
allowed by the SRV record. Just because pre-SRV protocols have to use
subdomains for scalability doesn't mean that is a good usability idea.

It implies that I should change my email address to dot@mail.dotat.at and
my Jabber ID to dot@jabber.dotat.at etc. etc. so that I can put their
certificates in the DNS.
