I don't really disagree, but in the case of SMTP/TLS afaik
some of the major service providers had to discover that
themselves before they believed it, and I can well imagine
the kind of reluctance that might exist within the set of
people who have to keep stuff working. A switch from Do53
to DoT or DoH is also arguably a bigger change so I'm not
too surprised that there are cold feet that may need to be
encouraged to approach the source of warmth:-)

Cheers,
