Yes this looks fine for notmuch-show. It won't work for search mode as
notmuch-show- commands basically only work in notmuch-show. I would
suggest copying notmuch-search-tag and tweaking it to use
tag-changes-with-local (as you have done for the show version
above). Something similar should work for tree-mode (ie copy
notmuch-tree-tag)

I think you will need separate functions for the three modes.
