Unfortunately printenv is not specified by posix (AFAICT it's a
gnuism) so that would likely break many other currently working
Would it be possible to do something like:

 'test -z `sh -c "echo $SSH_USER_AUTH"`' || fail "SSH_USER_AUTH present"

(plus or minus some quoting, probably) ?

usually comes from bad judgement.
