Better world export options

We already have the option to delete player data, but why can't we also delete entities? We should be able to do this for the sake of that one kid (me) that accidentaly spawns 1000 end crystals and crashes the game, I know this is small, but it's close to my heart, even just adding a video option to make entity models not load would be fine, just please Mojang, listen to me, bedrock players need this, java has mods to optimize this, and bedrock has none, I have searched the internet for ways for it to not come to this, but it has.
