Well, my reasoning was to minimize the risk of bothering people:
People using "dumb" terminals wouldn't be bothered because nothing
changes and people using "smart" terminals would see the message
only temporarily. Of course, emacsclient users would be the
exception. They would always be bothered and therefore I added
the "advice" switch.

That being said, I can also follow your logic. If we have such
a feature then we shouldn't surprise the user. We should make it 
consistently available in all environments.

I am on the fence here. I like consistency but I don't want to
bother Git users.

@Peff: Do you lean into either direction? Could you imagine that
novice/regular users are bothered? (I don't expect experts to be
bothered too much as they would likely be able to find and set 
the advice config).
