But anyhow, you work on the system and can't point out if this is an issue or not in the end-to-end sense? Like, why say OP is "missing the point" if you are not sure if they are missing the point?
TBF you do say "I'm not even certain that an extension that requests more than 5 permissions would be approved in the first place." Which if true, would make this pretty low priority.
(On the Empathy note, I just want to add: stating "Trust me you really don't want this job." In this context to random members of a forum is a bit of an empathy-lacking thing to do)
