Hi, coming from pydantic That redirect me to servo that redirect me here now.

The url validation specifis invalid host here I https://url.spec.whatwg.org/#host-invalid-code-point

But actually the host validation is partially implemented. A hostname can neither starts nor ends with an hyphen. But currently, this implementation says that -x is a valid hostname.

This is a parser, not a validator. There are many invalid parseable URLs. This is discussed in the section of the spec you linked to.
