Rust and Roslyn which also uses github both have essentially replicated
phabricator features to github to make things manageable. People often
ignore this on this off-handed remark that Rust uses github. This
is part of the changes rust which has the backing of a major sponsor has to
maintain to even start handling github. And I point out we have all of
those just build into phabricator.

And of all the tools I've used. Github has by far the worst interface to do
code reviews. It's handling of rebases which will wipe all existing review
comments when you push (collapsing them into oblivion) is very problematic.

I'm not even sure they fixed the bug that pushing a later PR with the same
branch name as an existing PR will permanently remove all review comments
from the older PR.

We're not special, we just don't want to trade a superior tool for a more
popular but inferior one.

Aside from being popular. Does github objectively have on redeeming feature?
