Ah, good point. I was misremembering and thought s6-log processed the
command string itself but used libexecline to teach it how, similar to
s6-ftrig-listen's dependency.

Looking a bit closer, the one that's going to break the hardest for
people using s6 solely as a supervisor is s6-notifyoncheck since you can
inline a check program with the -c option. I'm not sure how many people
go that route who aren't already going to have execline installed, but
it's something that will definitely cause some ill will.
