Giving edit privilege based on number of trustworthy edits
Once you hit 2000 reputation you gain the privilege to edit questions and answers even if you have never done so before, and therefore you might not know what is good editing etiquette.
Having your edits peer reviewed is painless so maybe it would make sense to have a number of accepted edits, in addition to the 2000 reputation, before you can edit without review.

A similar question has been asked: Giving edit privilege based on number of trustworthy edits, but I am not calling for a "trustworthiness" measure nor lowering the bar (actually I want to raise the bar slightly!) on how much reputation is needed to edit without review. Just suggesting that users should have some reviewed edits (say three) before being able to edit without review.
