Eventual sculk dimension balanced towards end game players

I know the Sculk dimension is a long ways away, but when/ if it ever becomes a thing please balance it towards end game players.

A player entering said dimension should need to have greatest quality of gear to stand a chance at survival, and should face situations where combat oriented potions are actually necessary. As the game is now it lacks challenge for those who have reached the highest quality of equipment to the extent potions are obsolete.

The general game should not be extraordinarily difficult, but I think an optional very difficult challenge is sorely lacking and the sculk dimension is the perfect opportunity to add one. A world guarded by walking natural disasters where you can obtain a compass that assists in locating where you have previously perished. It's really a perfect fit.
