You're welcome, and thanks for the quick reply!

We follow the usual kernel practice, so (B), though sometimes a user
is known to be incoming, so it gets added in a separate series for
convenience or similar.

But, yeah, in such a case, it should be agreed upon / explained where
it is supposed to be used, and the cover letter here should do that
(and you are completely right to ask!).

Cheers,
