I like it, but as a maintainer, I find this hard to know what to do with
it.

As a maintainer, I want to be reminded of what regressions have been
reported for my subsystem, so I know what to do and who to go poke about
them.

I could dig through the list and try to see if these are relevant to me,
but it's not always obvious.

How about something like "one email per issue" as a response from the
first report, that would cc: the needed maintainers (or people from
MAINTAINERS, you should be able to get that automatically from
get_maintainer.pl) and the subsystem mailing list (again from
get_maintainers.pl), so that I am constantly reminded that "you need to
get this fixed!".

Pester me, it's my job as a maintainer to get regressions resolved.  If
I see a long list with no names on it, It's easier for me to just ignore
:)

Anyway, I know that's more work for you, don't do it if you don't want
to, but as you have individual items in your database already, maybe it
is easy to do, I don't know.  Thanks again for doing this work, it's
great to see happen.

thanks,
