I wasn't sure that was possible. If for example the build is configured to
leave wavpack out that wouldn't work. Or is it assumed that fate is only
run with a ffmpeg build configured with default and some additions but
nothing default left out?

Considering the strict value, I guess I should also change the help text
then? Now it reads: encoding as 24 bits-per-sample, more is considered
experimental. Add -strict -2 if you want to encode more than 24
bits-per-sample
