In my experience reviewing tiny edits creates little to no burden on the reviewers. The backlog of ~500 flagged posts (where you often have to read the question, the answer and then decide whether the flag was really warranted) is much worse.
And then there is the other problem where edit reviewers have no clue of what they are rejecting and instead alienating the person who suggested the edit (rightfully). But that's a completely different point, admittedly.
Still, I don't think less-than-six-character edits would be a particular problem to handle as the edit review queue is often enough empty or very short.
