we’ll try downgrading to a commit before the aforementioned one now though and will report back with the results.

Moving downward to 4f7f9ef87cbcd574144f657dd43b7e705d98ff8e indeed solved the stuck PostAlert sidekiq workers and the OOM concerns: the few PostAlert jobs that do get queued now complete within a matter of seconds, not minutes.
