Limiting environment use for setuid/setgid programs only?

[Sven Joachim]

The ramifications of CVE-2023-29491 can be limited by configuring
ncurses with --disable-root-environ.  However, this disables all use of
the ncurses environment variables by the superuser which has the
potential to break scripts and makefiles.

Would it be possible to add a new option that only limits environment
use for setuid/setgid programs, like the --disable-root-access behavior?
