As with other folks, this is what we're used to, but it does cause a
lot of "polling" your tree to see what's landed. (And your "Pulled"
email to pstore today scared the crap out of me briefly -- it made me
go look for this thread...)

I enjoyed getting Greg's "Pulled" emails for post-rc4, since it closes
the loop. I've always hugely preferred getting "Applied" etc emails,
and I try to make sure I always send them too.

While this can work, I would find it personally only a little useful
since it doesn't actually contain the information I (and any folks
contributing to the pulled patches) need: has it landed? When I send a
pull request for security hardening things, I'm mentally wearing my
seasoned asbestos suit until I see the PR has landed. (Other trees of
mine like pstore don't tend to trigger rants, so those are likely just
fine for this notification method.)

This sounds like an annoying fragmentation of your workflow. I thought
Mark and Kirill's suggestion to stash the PR Message-Id in your merge
commit would be pretty easy to automate, though. (And may just be a
good bit of record-keeping anyway...)

On the balance, I think since most things you start to pull are, in
fact, pulled, the "send at start" method covers most cases and does
let people know when you've gotten to their PR. And I can spend less
time wearing my preparatory asbestos -- just from "Pulled" email until
I see it land. ;)
