<p class="MsoNormal">I also find the "Reviewed by" tag useful (as well as the review link), for the same reasons. In fact, I don't even use arcanist to push commits, so I do it all by hand, and only include the "Reviewed by" and "Differential Revision" tags.<u></u><u></u></p>

Maybe more advisory "you can remove the unneeded tags" might not hurt (but still adds to the length of new contributor documentation, etc, which isn't free) - though "Reviewed By" is useful (in addition to "Differential Revision") if it accurately reflects
who reviewed/signed off on the change (makes it easy when I'm reading the mailing list to see who's already looked a patch over, etc).<u></u><u></u></p>

These Phabricator metadata lines (`Reviewers:`, `Reviewed By:`, etc) are created automatically when the author uploads the patch via `arc diff 'HEAD^'`.<br>
The summary and metadata can be copied from Phabricator to the local commit via `arc amend`.<br>
<br>
Among the metadata tags, `Differential Revision:` is the most useful one. It associates a commit with a Phabricator differential (Dxxxxx) and allows the differential to be closed automatically when the commit is pushed to llvm-project master.<br>
<br>
The other tags (Subscribers:, Reviewers:, Reviewed By:, Tags:, and the `Summary:` line) are not useful. They just clutter up the commit message. Shall we mention on

https://llvm.org/docs/DeveloperPolicy.html</a> that developers are recommended to delete metadata tags before committing? It'd be nice if some pre-receive hooks can be set up to enforce deleting some really unnecessary metadata tags.<br>
