Another argument against the change: This proposal would only affect
/bin/test (or 'env test', or other constructs that force resolution
through PATH).  However, most shells have 'test' as a builtin, so it
will NOT impact those instances.  Having coreutils needlessly differ
from other implementations is undesirable.  If you can first get 'bash'
patched to do this, you might have a stronger argument, but bash is one
of those programs where the mere act of setting POSIXLY_CORRECT in the
environment changes a lot about how bash behaves.

bash is actually worse, since "[ --help"  doesn't work with the builtin. But agreed on your point.
