Yes, this is true.

The thing is, I don't see that template based drivers would be able to
stop beaconing :-)

This whole design that requires it seems a bit fishy to start with, so I
can't really imagine anyone writing firmware that supports it. That
said, ours only supports a single beacon at a time anyway, so we'll
switch immediately and don't have to do that anyway.
