TLDR; Whether they're left in on purpose or not, exploits are still flaws and mistakes, and it's not, in principle, unreasonable to want them gone.
I don't disagree with this take, if some "exploits" impact people's enjoyment of the game, it should be looked at. But it should not come at the costs of other's enjoyment. If it's an exploit that's so obscure and only being used by players that min-max the hell out of their game, then yes it should probably be fixed because they'd feel they HAVE to utilize it to play "optimally". However there are many things some consider "exploits" while for other's it's a fun feature and just a regular part of the game. I'm worried for losing out on things for the sake of players that cannot help themselves making use of 100% optional features(or exploits depending on one's perspective).
