Currently, there are some auto-approve checks that check if there were any other commits other than the approved author (for example, gcf-owl-bot). This is to ensure that malicious actors don't change code in a PR opened by a sanctioned author. However, this is overly restrictive in some cases, for example this pr wasn't approved because there was another author, danielbankhead. However, his commit was merging into main. Perhaps we want to ignore merges into main, or sanction an extra group of github users (i.e., those belonging to googleapis?)

@chingor13, lmk if you have any suggestions!
