It would require a bit more effort to adapt it so we properly handle bounces,
but effectively this does what you're asking about -- replies sent to a thread
will be sent out to all addresses we've associated with that thread (via
get_maintainer.pl). In a sense, this will create a miniature pseudo-mailing
list per each thread with its own set of subscribers.

I just need to make sure this doesn't fall over once we are hitting
LKML-levels of activity.

How does that square with the "subscribe by path / keyword" concept?
If we can do deep magic of this sort can we also use it to SMTP to
people what they wanted to subscribe to rather than expose it as
POP/IMAP/NNTP?

Well, people can subscribe without needing to become an M: or R: entry in
MAINTAINERS. I guess that would be the main difference.
