So this means that if I only want to do the equivalent of:

   gce-xfstests -c overlay generic/013

as part of a bisection search, it's impossible to do this via the
config file and "./check -s ext4-overlay generic/013" alone.  Someone
who wants to do this will have to use their own wrapper script to
format the base file system with the proper file system.

Correct?

Which is fine, I have my own wrapper script system.  :-)
