I'm curious why I wasn't pinged in this PR: NixOS/nixpkgs#211126 (as a pahole maintainer)

According to the ofborg-eval-check-maintainers action I was listed as a potential maintainer: https://gist.github.com/GrahamcOfBorg/03fefe23cc2d730a4ac58f66d28872ed
But I didn't receive any notification, nor see anything on the pull requests that'd hint I was mentioned.

Is there a limit to the maximum number of people being notified, or something like that?
