i also have to recompile my kernel all the time to enable it and i am
running with this since beginning of 20.04 release. it would be nice if

user if they want to configure them or not.

involving Transparent Huge Pages that warranted turning them off. That
bug is long-fixed in arm64, but the raspi kernels appear to be keeping
it as a

Title:
Large Page support disabled on Raspberry Pi
I believe 'transparent hugepages' are still disabled in the latest
kernel configs, creating a significant barrier to THP usage (having to
