This is more than half of my code reviews (when functionally correct). It works pretty well, when you can trust that the person doing the changes won't accidentally (or otherwise) slip in behavioral changes. Like half just got merged as-is and half of those got a separate cleanup later.

Most people are fine, some routinely abuse it to do much larger changes that should normally imply full review - double check afterward! Your name is still on it, it is still your responsibility.
