I'm afraid I'm having difficulty picturing what it is that you're
looking for.  The proposal incorporates, by reference, all the
documentation for 'used' and for 'all', and the way to use it is no
different.

If there was documentation on how to choose between e.g. all and used, I
suppose I could build on that to add this intermediate choice, but...  I
can't find any such docs, and I'm uncertain on whether adding that would
be useful to begin with.

Did you have something else in mind?
