Yes, sorry. I presented two arguments. Only the one about copycat SSIDs is
yours.

Okay, so we're not talking about wholesale containment of the copycat AP,
but rather management of our own client devices which, by definition, we
can't interfere with. Because they're ours.

That approach sounds perfectly reasonable. I wonder, absent certificates,
how one can be certain about the identity of the client, and if such a
narrowly scoped containment mechanism is actually implemented by the
various checkboxes available to enterprise wifi administrators.

Is it clear exactly what "enterprises going rogue protection" are up to?
I've asked several, gotten wildly different answers. Keeping "my clients"
off "copycat APs" sounds reasonable. More aggressive action might not be.

Thanks.
