For files that have no specific maintainer, the
default period for reporting commit sign-offs and
authors as possible interested parties in a patch is
1 year.

And given how little my sweet wife likes me when I
swear around her, I'm not inclined to do that
specifically for you, no.

That was Andrew Morton's idea.

That's an assertion, but you've neglected to give
a rationale for it.  I think authorship is quite a
good reason to be cc'd on something as given that
you've spent the effort to originate code, you're
also quite likely to be interested in patches for
that code.

If a get_maintainers.ignore file is created,
(which seems like a reasonable idea, thanks),
I'm not maintaining it.

Maybe this: (if you create a .get_maintainer.ignore file
with your name in it like)

$ cat .get_maintainer.ignore
