This brings something else to mind for me.  Another advantage of GitHub
is that there are many tools out there that work with it.  Not so much
for Phab.  As an Emacs user, getting access to magit/forge's ability to
interact with GitHub PRs would be amazing.

Absolutely.  Reviewing a patch series has always seemed a bit counter to
LLVM's development philosophy of small, incremental changes.  I
understand the need to provide context for large changes (I have posted
mega-patches in Phab for that purpose), but the path to get to the large
change has always been small, incremental changes.

We have used one-commit-per-PR in our downstream for quite some time now
and it works well.
