Add some inline information, what the macro is used for, why it came to
be and what we shouldn't do if we consider further deprecation in the future

I think this is a fairly good start.

Note: I've intentionally omitted any text about handling future
deprecation. There's none, yet, and stipulating about something
that may or may not happen in the future isn't the best of ideas ;-)
