One option is to create symlink farm. Since it's only directories being
symlinked, it isn't that bad.  I don't know how well this scales, but it
seems to work for about 200k messages in 184 mailing lists. Roughly
speaking:

% mkdir list
% cd list
% ln -s ../.list.* .
% mmv .list.* *  # zsh specific, optional
% notmuch new

Notmuch new took about 10 minutes, but now I can search

'path:list/**'

to add a second level

% mkdir debian
% cd debian
% ln -s ../debian-* .
% notmuch new

Of course this could be scripted.
