Is it not possible to just have an added option to unset to make it
use old behavior without needing to use compat*?  Compatibility mode
affects general behavior and this isn't always something I'll need to
keep my scripts compatible.  In the manual I read "It's intended to be
a temporary solution" implying the script at one point should upgrade
its minimum version requirement and that's not what I'd want.
