These changes LGTM, minus a nit in the CHANGELOG.

question(non-blocking): There doesn't seem to be an impetus for these changes. Are you hoping to "just" reset the set of changes since the last revendoring, or were you hoping to unblock something?

Approving, with merge conditional on consensus for the fix I pushed with 79d85ee.
