I'm strongly in the "well just don't do it, then" camp. And I write as someone who's definitely not any sort of hardcore player...
While I can certainly see why people would prefer this suggestion to be an option/a hardcore feature, I think "well just don't do it, then" should really stop being an argument. You can always choose to make a game harder for yourself by not doing advantageous things, but that doesn't make the gameplay rewarding. For me, knowing I could just use cheese to solve an encounter actively devalues my enjoyment for playing traditionally, because I'm choosing to play "poorly" for no-tangible benefit. Why should I feel fulfilled beating an enemy after 7 grueling rounds when I know that I could have just one-shotted the enemy with a trick? It makes me feel like I'm wasting my time/making my characters weak by being original with my gameplay, rather than doing the gimmick the devs built into the encounter.
So I can understand why people may prefer to make some changes optional if they happen to enjoy the trick/cheese, but simply saying "don't do it then" ignores the fact that intentionally playing a game sub-optimally, or knowing that the boss you are fighting can be defeated easily with a gimmick, actively destroys many people's enjoyment of the game even if they don't use the cheese themselves.
