What about simply providing an API that takes a bunch of tag
operations and applies them to the current thread/message/region?
Maybe even the notmuch-show-add-or-del-tags that you have below
(probably spruced up a bit).  I feel like the type of people who are
likely to use tag macros would also have the know-how to add a simple
key binding of their own, assuming it *were* simple.  Such an API
would probably clean up some of the tagging code in notmuch-show, too.
