Agreed that extending the encode function is the way to go. An example
of that is the recently added support for base64url:

I've definitely used base32 to encode uuids myself. The primary
benefit being shorter strings, while still being able to spell them
out by voice to people without having to specify whether a letter is
upper or lowercase.
