Option to limit dimension roof to y=128

[md500]

I want to limit roof from 255 to 128 to allow compatibility for Bedrock users with GeiserMC Plugin.

If I try to log from bedrock, nether is incompatible (because bedrock only renders 128 blocks) and I must enable "the end spoff compatibility" but the experience is different (red fog, end song and green tone, it basically makes nether look as the end)

It will be possible to be added in the future?
