Of course some would ignore it.  Many registrars do blind create

I had no intention of suggesting that the server side (formally, the
repository in EPP-speak) needn't check input.  I personally would
prefer that gTLD registries do more validation, not less, and I think
you're a moron if you don't check your input for minimal compliance
with your own policies.
