Yes I do. I dont have in my head all possible 2^X values, but K, M, G,
T : thats ok (less neurons needed)

You focus on current x86_64 hardware.

Some arches have lot of different choices. (powerpc has 64K, 16M, 16GB
pages)

In 10 years, you'll have pagesize=549755813888, or maybe
pagesize=8589934592

I pretty much prefer pagesize=512GB and pagesize=8TB

This is consistent with usual conventions and practice.
