I see your point, but I usually start with the Guix service
documentation and it clearly would state "TLSv1.2 TLSv1.3". If your
client doesn't support TLSv1.2 (thats 12 years old), it's maybe a better
idea to fallback to HTTP...

I think in general its a good idea to follow upstreams default, but it
should not hinder us to make more secure defaults

Hm, I try to keep stuff simple and to be honest all those service
"matroska" stuff grows over my head. If theres an error I can not debug
them at 2am or at any other time...

A compromise would maybe something like :
(ssl-protocols %upstream-default OR %mozilla-default OR "Your custom
string")
