That is indeed interesting.

I have slightly different goals for my version. I want everything to fit in 128 bits so I'm sacrificing some of the random bits, I'm also making sure the representation inside Postgres is also exactly 128 bits. My initial version ended up using CBOR encoding and being 160 bits.

Mine dedicates 16 bits for the prefix allowing up to 3 characters (a-z alphabet).
