Required fields are not required in the registration form

No I am not.

Actually the minimum password length in Joomla is 4 chars anyway, so there is no chance to register without a password.
That would throw an error.

The only thing you can do is order as a guest without registering and therefore no password.

Please allow me to disagree with you:

Missing password will pass because Joomla! allows you to generate random password when the input password during registration is empty.

Ok,

but then you actually have a password. So if you stop that via JS that should be fine.

If someone bypasses the JS "maliciously" that someone will have an unknown password.
If you don't know your Joomla password you can reset it anytime via the J login.

So  I actually don't see more than an theoretical problem, that is also no security issue.

OK thank you.
This is your decision.
