Actually +64 above/+64 below is only the new default. Custom worlds will be able to increase the world height limits to +2032/-2032. That leaves a lot of room for activities. I think custom terrain gen data packs like the one mentioned above still have to be adjusted to actually use the full height.
I'm excited for mappers that can now build 1-1 scale recreations of real and fantasy locations like everest (~4000m from the base), minas tirith (300m), barad-dur (1400m), courisant senate building (600m), etc.
