They've already got the thousands of different names. Adding a second
to the DNS provisioning mechanism won't be that hard.
In case it wasn't clear, each customer sets up his own DNS and CNAME.
This means that if the mail provider adds this feature, they have to
contact several thousand resellers and get them all to update their
DNS. I would characterize that as hard.
You've postulated a particular, idiosynchratic operational environment with
thousands of administers. There's nothing "wrong" with that environment, but we
need to be careful that we don't require that it's characteristics dictate
design requirements for everyone.
Basically, with an environment of the sort you describe, everything is
relatively more difficult.
While it's fine to try to design something so that it's scaling characteristics
are /better/ than linear, but it's typically also acceptable for it to be linear.
