As you wrote them "in no particular order", I'm going to respond

thanks for the additional examples, but so far, this matches my
understanding of the situation. I certainly wasn't thinking of
ICANN as an authority, which however does prevent me from
applying insights gained while working on projects in its sphere.
Using text as an identifier (as opposed to IP addresses) drags with
it all the messy, conflicting and sometimes self-inconsistent ways
in which communities use text.
Sometimes that is expressed as being a problem of "Unicode",
when in fact it is not.
