My expectation is without "maybe warn about it". And not adding it
as an alternate (because it is not usable) is just "doing as I was
told to do", nothing noteworthy. Because "do it only if you can" is
an explicit instruction to the doer that the caller does not care
about the outcome, I'd think there shouldn't be any warning, whether
it is used or not. At the same time, if the caller wants to know
the outcome, and using if-able as a way to say "I prefer to see it
happen, but you do not have to panic if you can't", I'd think it is
OK to give "info:" to report which of the two possible paths was
taken in either case. Throwing a "warning:" only when it didn't do
so does not make much sense to me.

I have no idea what this sentence means.

Yes, and if we were to go that route, "clone" without "-v" should
not report which of the two it took. It is OK for "submodule" to
look at what "clone" left as the result and do more intelligent
reporting that is better suited for the context of the command.

If the user says "--recursive --reference", then the user probably
deserves to be notified. As I said (eh, rather, as I wanted to say
but failed to say so), I do not have a strong preference either way.
