Not just a decent implementation; an implementation which meets the spec. This is not a problem with OAuth2, which explicitly requires registration of URIs where the implicit grant type is used, and covers other cases well in the Security Considerations section.
It's just that with a decent implementation, you should also be required to register it beforehand with the provider.
