there have been periodic proposals to reduce chaos in
the DNS and on the Internet by getting of all gTLDs that do not
serve an obvious international purpose and restricting TLD
labels to ISO 3166-1 alpha-2 codes and a _very_ small number of
exceptions, none of them involving non-Latin characters.
While to the making of many proposals is no end (to paraphrase an early source), this doesn't mean that they are likely to go anywhere. Adoption of any such proposals would run into very serious headwinds in regions that see this as a perfect issue to assert national identity via domain names.
That alone would be a good enough reason to not spending time on mentioning them.

PS: it's not clear to me whether "strings" as means of accessing
resources that are exposed in the UI or document contents will
remain the preferred technology. So far, search and the use of
apps have resulted in some inroads, but we are still far from an
inflection point. If and when we reach it, any of these
considerations, but also the proposals you mentioned are
automatically moot.
