lists.gnu.org allows to map Message-ID to URL as well:

https://lists.gnu.org/archive/cgi-bin/namazu.cgi?query=%2Bmessage-id%3A87tuolhyl7.fsf%40posteo.net&idxname=emacs-orgmode

Unfortunately I have no idea how to get Message-ID having a link to 
particular message on lists.gnu.org without search by e.g. subject and 
author.

I had an impression that mailman mangles links like
https://list.orgmode.org/87tuolhyl7.fsf@posteo.net
since they resemble email addresses, so should be protected from 
spammers. I do not have links to prove it for mailman but debbugs 
certainly does it. In this sense links to lists.gnu.org are safer:
https://lists.gnu.org/archive/html/emacs-orgmode/2021-04/msg00133.html
A cheat for debbugs maybe the following: replace "@" to "%40" 
https://list.orgmode.org/87tuolhyl7.fsf%40posteo.net/T/#u
(Message that I used in these examples: Juan Manuel Macías. [tip] search 
this mailing list with helm-surfraw. 2021-04-05  9:25 UTC)

list.orgmode.org (public inbox) is an ordinary subscriber just as you, 
so it can not add any link to messages delivered to you. There is a 
dedicated header Archived-At that mail list may add, unfortunately 
mailman does not know URL at the time of message processing, so it adds 
only a link to whole archive as List-Archive.

https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/handlers/docs/rfc-2369.html#archive-headers

Curiously news.gmane.io still adds Archived-At despite web interface was 
disabled years ago.
