I was not there at the creation but I find it worrying to rely on the
recollection of one specific person. The "alphabetic-only" rule in RFC
1123 is just a side note, never detailed, and presented as a fact
(which it was at this time), not as a mandatory restriction.

It is nice to remove the ambiguity (and therefore
draft-liman-tld-names is a good idea) but it should be treated as a
small adjustment, not a big reform.

I completely fail to see why. Most reasons given were policy
issues. Here, I fully agree with Edward Lewis's law "bus drivers
shouldn't determine the bus route". There are no *TECHNICAL* reasons
to limit TLD to alphabetic characters. There may be non-technical
reasons and even valid non-technical reasons, but they are completely
off-topic for the IETF.

The IETF should be really careful not being used as a pretext in
policy disputes. If some governance body wants to prohibit IDN in the
root (which is the case today), they must not be able to say that it
is per-request of the IETF. Because this would drag IETF in the line
of fire.

This would turn a small ambiguity in RFC 1123 in a real rule. -1 for
me.
