as the author of D14104, the advisory update proposal here would make me happy. Its basically taking the class of comments that are suggesting specific fixes or additions and making it more lightweight. One minor ui problem to solve would be supporting pure inserts or deletes.

@mjlyons, if its a one-time thing you could just pull the data directly from the db. If its ongoing, IMO its really easy to write a custom, one-off api method

just a heads up that I'm not actively working on this any more (have to finish other things before my contract ends.)
Last time this was discussed, @vishal proposed tweaking our current APC settings.

Renaming to arc lint + arc unit sounds good and clearer to me.

/changes/inline is new and has only existed for <1 week, btw

New startup tab for creating an inline comment:
