Yes, the ability to pause a domain from the toolstack command line was added
way back in the beginning largely because... Well, because it could be done,
and it was easy! It's not actually a very good idea. You won't actually find
the toolstack itself automatically pausing a domain in very many places at
all -- most places where it does are debug/diagnostic code, or where a
domain is about to be destroyed anyway.

So, yes, in short: don't do that! :-)
