Looks reasonable (I think you can take my opinion as approval in this case
- but I guess you sent it out for review looking for other feedback too,
perhaps). If it interests you, it's probably also worth highlighting the
"recover as written" requirement which isn't entirely clear/explicit in
those docs (and the implication that has on fixits on warnings: that they
cannot change semantics - they have to be the "suppression" fix at most
(which means there are very few cases where fixits on warnings are valid
(since if you're confident the warning is good then the chances are that
the suppression is not the right fix)))
