On windows I expect fallback to `browse-url-default-windows-browser` by 
default. Are you able to open mid: links from e.g. cmd.exe?

     open "mid:63dd2b57.050a0220.ed66f.0117@mx.google.com"

Looking into https://bugzilla.mozilla.org/show_bug.cgi?id=1696218
"Thunderbird displays the dialog for default application after each startup"
and the patch, I expect that thunderbird on windows can register 
protocol handler for the "mid" scheme.

Unsure however if the following entries in advanced preferences are 
relevant:

network.protocol-handler.expose.mid	true	
network.protocol-handler.external.mid	false

I have never debugged protocol handlers on windows. I would compare 
"mailto" and "mid" entries in the registry

I am trying to determine if it is difficult to get mid scheme working 
system-wide and emacs-wide on windows. If not, I would just add your 
example "[[mid:$msgid$][$author_name$: $subject$ ($date_iso$)]]" to the 
remark related to copying Message-ID in the existing text and corrected 
a bit a note on obsolete thunderlink. If thunderbird still has issues 
with registering global mid: handler then your snippet with 
`start-process' should be added.

Maybe I just have gone too far trying to add "right" recommendation.
