Yes, it should have the same trailer as the original commit, otherwise it won't be correctly tracked by Phabricator. A "rework" isn't special, it's revert, reopen the revision, update the revision and land the revision again. If re-review isn't needed then you can skip some of the middle, but that's it. Though in this case I do think re-review was warranted, the new clang dependency seems a bit dubious and hints at the design not being quite right.
