ST_MakeValid by definition does anything it likes, the only thing that should happen: output is valid and no vertices are lost. The "no vertices are lost" forbids to discard the hole. If MakeValid will change behavior there it will stop being useful for "inners and outers are marked incorrectly" case and won't be exactly useful for yours, so I'd not touch it.
