Ah, good to know!  I've added special-case code paths for the Sun version to
use ``, more to document the issue than anything else since it's otherwise
identical to $().  For anyone else needing to do this all it takes is:

# shellcheck disable=SC2006

right before the comment about Sun braindamage that precedes each `` use.
In my case I just integrated it into the comment about Sun:

# shellcheck disable=SC2006 # Antediluvian Sun tools
