That may be so, but it pales in comparison to the challenge of handling usernames properly in applications. This is especially true when multiple applications are involved, and they are all supposed to agree on what characters are, and are not, allowed. The Debian project is facing that problem right now, as two user-creation utilities disagreed about which names are allowable. A plan is in place to sort this out before the release of Debian 13 ("trixie") sometime next year.
