This is correct. Usage of Arcanist also makes other commit metadata visible.

The only thing needed here are changes to Phabricator to allow it to
extract authorship (and other useful metadata) when dealing with the
output of "git format-patch" and "git show". At the moment changes to
Differential aren't a priority for upstream, but they have indicated
that it is something which is doable so if we submitted a patch it is
quite possible we'd get it integrated.

Much like being able to submit patches using "git push" which is also
on their radar, and which they've also undertaken some of the
technical investigation for.
(Although technically this is much more complicated as you have to
replicate the Git protocol)

One possible way forward way here would be to utilise a custom field
which can show the necessary authorship information.
We'd have to write the necessary code to do that though.

I believe Wikimedia did something similar to link back to their
central accounts system for user profiles.
