I believe this is caused by changes in the nether's surface generation, which might have something to do with the surface rules.
In noise generation stages, it still generates the bedrock like it usually would,
but at the surface generation stage these bedrock layers get replaced by regular surface blocks (which does not happen in 21w42a).
Making sure that these surface terrain generation stages cannot replace bedrock blocks fixes this issue
Seems to be more than just missing bedrock on the ceiling, I have basalt delta generation extending up to at least y140, with even higher generation in the distance. Seed: 8182480240926874054 cords: -15 150 5

I am able to confirm this behavior. This also affects the bottom of the nether as well.
