to be fair, it might be cool with an "option" to wipe out and "restore" some dungeons to what it was primarily used for before they became a source for enemies for a sense of creativity in basebuilding and using caves as a part source entrance inside of someones basement or something

but leaving out "optional" when people might need it to replinish resources is really critical to replayability as some just dont have the time to wipe their world seed clean for the sake of "replayability"
