An alternative would be to ignore any .notmuch path with a xapian
sub-directory. This would mean if a user indexed some subset of their
mail before trying to index the whole thing they wouldn't accidentally
index the old xapian database. 

Alternatively we could just view the above as user error. (If a user
wanted to have an index for a sub-directory they would have to use
excludes to exclude that index from the full-directory index).

Best wishes

Mark

I think the above was suggested by rlb on irc but I don't think it got
any reply.
