I rolled patches for this in the past, see the following message:

id:"1310874973-28437-1-git-send-email-anarcat@koumbit.org"
id:"1310874973-28437-2-git-send-email-anarcat@koumbit.org"

They were indeed refused by the community, but I felt they were still
useful.

I do not use those patches nowadays, however, but to me they would fit
in a broader architectural view of notmuch, where tags are not only
metadata sitting outside of your email, but is also written to the
messages themselves.

The idea is that you can then run notmuch from multiple places without
having to worry about synchronising your tags manually: the tags would
sit in the messages themselves.
