Only because it used to work like that and it is a bit confusing if
the behaviour changes suddenly.

To get information about unknown fonts, I used to put them in some
temporary directory and call "fc-cache ." there, then I looked into
the cache file.

As the caches are now (usually) generated in /var/cache/fontconfig, it
has become a bit inconvenient anyway to find out which cache file
belongs to which directory, therefore I guess you are right that it
doesn't matter to loose that behaviour.

If I want to check what cache files are generated for some new,
unknown fonts, I'll have to add the temporary directory to
~/.fonts.conf now.

That's no big problem, therefore I think you are right that we
can forget about directories which are not subdirectories of
directories listed in a .conf file.
