Better, Bigger, and More Dangerous Dungeons

As the title says, we need better dungeons as I mean all of the dungeons, the nether fortress, desert temple, jungle temple, stronghold, mineshaft. These dungeons need to be more up to date with modern minecraft these dungeons need to be bigger and tougher. I know that minecraft isn't suppose to be super tough since its a kids game. But you could at least add few spawners, and maybe some traps to desert and jungle temples, make them bigger since they feel small. Strongholds should be tougher and bigger add some spawners in strongholds too, and add some more rooms like a armory  to the stronghold it is the only way to get to final boss, so it should put up some what of a challenge to see if your worthy enough to beat the ender dragon. mineshafts are bland they should be more detailed. The nether fortress is also bland, it is also the only place to get wither skeleton skulls and blaze rods, and after that its useless. So you should add more chests that have some good loot in it, it should also have more rooms like a armory, and it should be detailed more. Maybe add some more dungeons so its worth exploring instead of just trying to find rare biomes on your world which may take to like 3 hours to two days.
