Many out each family in its own dir, and even if not man users move
each family into its own dir when installing, to ease the maintenance
headaches if they do not want all font families in the search tree at
all times.

OTOH, that is also a distinct possibility.  John, can you check that
box for its <dir/> entries?

That is a good point.  I suspect you'd loose the ability to run
fc-cat(1) to grab info about the fonts in a given dir -- something
I got used to using the old, ascii cache files for -- but otherwise
it does seem beneficial.
