It's funny, because the first time I saw a reply from Greg on a pull
request, I thought I had done something wrong -- I've been so used to
only getting replies when there's something not right with it.

Like others, I'm used to polling for material showing up, and either
way is fine with me.

For pull requests we do, we normally reply (since it makes it easier
to see what pull requests have been handled when you share them). In
my case, I write the reply immediately, but I use msmtp-queue and mutt
to do it, and don't send the queue until I'm done with the current
batch of pull requests, so I sometimes go back and revoke a message
before it has gone out. It doesn't work for web-gmail use cases.

1 + the last follow-up would be fine with me. I doubt anyone will just
delete their material within minutes of getting the initial reply.
