Claiming that Base64Url is a problem due to one or two [marginal] implementations seems counter-productive.

The abundance of systems based on the JOSE stack set the de-facto standard for Base64Url: https://tools.ietf.org/html/rfc7515#appendix-C

A human-readable backup-key consisting of 20 or more characters would probably also need to be divided in sections like a credit card number as well as having a checksum.  A backup/restore facility could deal with that, making you independent of the computing system's representation of data.  Bech32 seems like a pretty good candidate for "human-readable" data.
