It's different in that the PR author doesn't have to do it. Automation will remind the reviewer that the PR needs merging after it has been approved.

And I agree with @tstellar that I'd prefer that over the more involved process proposed here.

I think the only thing I'd suggest is to delay that comment until all CI workflows on the PR have completed (either success or fail). Otherwise I have to remember to come back to the PR after CI is finished.
