These key names are table entries in an IANA table, and never go over the
wire.
So, while it might be a reasonable design choice to limit the character set
to match DNS labels, i.e. US ASCII, that's not technically a requirement.
I'm not suggesting doing otherwise, but, it should at least be called out
as a conscious decision.
Maybe an alternative solution would be "any valid A-label", which would
potentially support UTF table entries encoded with puny-code?

As for length, as long as it is long enough to encode "bikeshed-colour", I
don't really care. :-)
