Does emacs support query to desktop environment if specific URI schema 
is supported? Anyway it will increase load time. Instead list of types 
for `browse-url' may be converted into a user option, currently it is 
hard coded:

(dolist (scheme '("ftp" "http" "https" "mailto" "news"))
  (org-link-set-parameters scheme
                           :follow
                           (lambda (url arg)
                             (browse-url (concat scheme ":" url) arg))))

Currently I use

(with-eval-after-load 'ol
  (org-link-set-parameters
   "mid"
   :follow (lambda (url &optional arg)
             (browse-url (concat "mid:" url) arg))))

See Org FAQ https://orgmode.org/worg/org-faq.html#org1d563f2 "Can I 
create links to Thunderbirds emails?"

I suppose, notmuch may provide a function for "mid:" associatiopn in 
`browse-url-handler' and a .desktop file similar to

http://git.savannah.gnu.org/cgit/emacs.git/tree/etc/emacsclient-mail.desktop

for handling mid: links from other applications.
