It's been mentioned a number of times that users should feel free to post basically whatever on their local metas (instead of bringing them here to Meta.SE), since the Powers That Be (devs? community team?) monitor all the child metas.
My understanding is that this is at least partially automated - the Powers That Be can view feature requests across all metas, or bug reports across all metas, or what not. (At least, I sure hope it is! Having to trawl 100+ meta sites manually sounds terrible!)
This being the case, are there any rules or guidelines about what kinds of questions should be tagged with bug and feature-request on child metas? I mean, obviously bug reports should be tagged with bug, and proposals for new functionality locally or globally should be tagged with feature-request, but what about e.g. requests for a site's moderators to do something like synonymize or rename a tag, or proposals for local policy changes?
The reason I'm asking is that I noticed that a global-♦ person came by and removed the feature-request tag from a question on a child meta - so I was basically wondering if incorrectly-tagged posts on child metas are causing trouble further upstream, and if so, what users of child metas should do to mitigate this.
