That sounds reasonable to me.

Given that named queries are already stored in the database (even though
considered part of config), it sounds very doable.

I’m not sure this is relevant, if the configuration is stored in the db.
Especially comments.
Again, named queries as a case in point.
A simple `notmuch config list` is “esport”, `notmuch config set
--batch` can be added.

However, all this sounds as an entirely independent proposal, even
though a reasonable one.

It is a much bigger change than potential options for solving the
problem that I raised,
and, most importantly, it doesn’t even solve it, because the
difficulty of discovering the db,
with all the falling-back logic and relative paths would remain
_exactly_ the same.
