In detail

The vendor's pages still describe validate-envelope and validate-recipient with a default of strict. Neither is printed by this build's help output, while strict-email-addresses is — and the binary accepts all three, so a configuration written from the documentation will not fail, it will simply be governed by directives the product no longer advertises. Which behaviour actually wins when both are present is untested, and that is the kind of ambiguity worth avoiding: write the printed name.
