On the plus side: it works. Here is my interpretation of the idea:

% cd ~/Maildir
% mkdir .NM_myTopLevelFolder
% ln -rs .myTopLevelFolder* -t .NM_myTopLevelFolder
% rm -f .NM_myTopLevelFolder/.myTopLevelFolder
% notmuch new
% notmuch-mutt --remove-dups --output-dir ~/Maildir/.=Search \
         search keyword and "path:.NM_myTopLevelFolder/**"

So, thanks for this workaround suggestion.

On the downside:
- It doubles the number of messages to index (though then even 
multiplied by two, my 300k messages are Not Much Mail™ - but still...)
- myTopLevelFolder gets a NM_myTopLevelFolder twin and restricting the 
search scope to it requires using its twin's name
- The additional messages are duplicates, so --remove-dups becomes 
mandatory in any search query
- This method is good for restricting the search scope to a directory, 
but not for excluding a directory from the search scope... Which alas is 
what I desire most...
