Thank you for filing a feature request.
As long as notmuch, notmuch.el and ol-notmuch are there we have a viable
solution, thanks to this (undocumented) trick with notmuch:id:123abc, after
getting the id by opening the mail with notmuch in emacs and »c I«.
Less than dozen lines of code in init.el (configure mid: links in Org
and install notmuch handler for `browse-url') should allow referencing
messages in a MUA agnostic way at least by Message-ID. Emacs mail
clients allows other queries, but likely there is no standard for them.
This is weird since ever. I've been talking to some collegues and everybody
has his/her own special approach. Mostly producing a PDF from the E-Mail and
saving this and its attachments somewhere. That's a thing that bothered me for
decades.
Thunderbird allows to save messages as an .eml file and to open it by
thunderbird /tmp/test.eml
Gmail web application allows .eml export as well. In some cases it is an
alternative to PDF.
