I am on a mostly same boat but doing a bit better ;-) in that my
daily driver is a point marked as 'jch', somewhere between 'next'
and 'seen', that appears on "git log --first-parent --oneline
master..seen", and this serves as a very small way [*] to see
breakages by others before they hit 'next'.

    Side note: This does not work as well as I should, because my
    use cases are too narrow to prevent all breakage from getting
    into 'next'.

I'd recommend against anybody using "seen" as their daily driver.

Being in 'seen' merely is "I happened to have seen it floating on
the list", and the only guarantee I can give them is that I at least
have read sections of their code that happened to conflict with
other topics more carefully than just giving a casual reading over
them.

If CI is broken for more than a few days for 'seen', I may look at
them a bit more carefully, only to see which one is causing the
breakage.  But that is not necessarily to fix the breakage myself
but to just eject it out of 'seen' ;-).
