Request: Links to existing implementations which utilize UUIDs and already encode them in some alternate format

[kyzer-davis]

For example,

ELK seems to utilize Base64 UUIDv1/UUIDv4:
[elk] cluster UUID [FAxrPE-sQluvrDS_2HvlSQ] and source code.

Short UUID Library generates Base57 UUIDv4:
KwSysDpxcBU9FNhGkn2dCf via source

I am actively looking for others to investigate trends to take back to the considerations table of the README.

Any links that can be shared will greatly help.

Looks like it encodes the dashes though?
