I have a bit of trouble parsing this last paragraph.

There are two possibilities:

- The offer/answer is incomplete, so we don't know whether BUNDLE will 
be turned on or not. (This can happen only in updates - you can't do ICE 
checks before choosing the BUNDLE address in the initial exchange, since 
you don't know the remote candidates)

- The offer/answer is complete, and both parties know the BUNDLE address

In the last state, it's impossible to do anything BUT check connectivity 
for the whole BUNDLE group; there is nothing else to check for. So 
RECOMMENDED doesn't make sense; it's not even a MUST, it's just the way 
things work.

In the first state, I think it should be RECOMMENDED to delay checking 
until you have completed the exchange, so that you know what the BUNDLE 
address is. But that's not what the words seem to say.

Could you clarify?
