I'd love to put this into shape to become part of notmuch proper. 

My question, for this and other things I've worked on, is where code
that targets message-mode should go. In notmuch-mua.el? Or a new
notmuch-message-utils.el? Or just a catch-all notmuch-utils.el? Once I
know where it would make the most sense to group these, I'll submit a
patch.

But just to clarify: you don't mind if removal is a customizable user
option, right?

Best,
