As an alternative approach would allowing a list of tags (or even tag
changes) to apply when a message is "read" do what you want and be more
flexible? I am thinking of something roughly analogous to
notmuch-message-replied-tags. I can imagine some people would like to
remove the inbox tag automatically for example. (And since we sync with
maildir flags the exact tag name does matter).


I agree with Austin that the current unread marking is a little
weird/unpredictable (eg notmuch-show-next-message marks a message read
even if it is closed) but I don't think fixing that helps your use.
