The problem with _marid subdomains is that they break wildcards, since
DNS wildcards don't permit _marid.*.foo.com.
I seem to recall at the WG meeting that people *did not object* to
breaking wildcards. If I am incorrect I'll be happy to retract, but we
should probably refrain from rehashing what I'm pretty sure is a
discussion that has been archived around here once or twice.
