I don't see this as related to active/active. I think it's related to
running critical services non-HA on an HA server.

Right. So they aren't HA. That doesn't sound like my problem ;-). And,
if you make it HA, then it'll fail over - and you'll be happy ;-)

You can hack the EVMS script to return success on stop. You can make the
script lie if you like. I'd go for that before I tried to bless this kind
of configuration by modifying the base code...
This CAN CORRUPT YOUR VOLUME INFO. Don't think this is somehow never going
to happen to you. On the other hand, you'll probably get away with it for
a while before you get caught - because people rarely modify volume
