Yes, tuhs.org:80 &443 could permanently redirect to www.tuhs.org so browsers update to the full canonical name (assuming that's the desired name).

Though I think Norman was drawing an analogy between A-records/hard links and CNAME/symlinks, then observing that prior to 4.2BSD in 1983 there were no symlinks only hard links, ditto CNAMEs in RFC-882, also 1983.
So if we're going back further, we shouldn't use them (it breaks down a little when considering A-records though, since we can't easily not use those!)

Surely a site that aims to collect information should have a single
canonical name, not multiple ones that lead to the same content on the
same host.

I would suggest to pick either www.tuhs.org or tuhs.org as the HTTP
hostname, and make the other redirect to the first (or remove HTTP
service from the not-chosen one entirely) only so as to not break
existing links from elsewhere.
