I think we can close this, yes.  Basically, you are saying that most
of these warnings will go away once we get our act together and fix
all the missing 'require's.

Btw, I think the doc string of comp-async-report-warnings-errors could
use some love: as it stands now, I needed to read the code where it is
used to understand what it does, and why it is a defcustom.  Some of
the explanation you, Andrea, wrote in this thread could find its way
into the doc string and make it much more clear.

Agreed.

Thanks.
