host: .uber.com should be disallowed

[mohsen1]

The host regex was not able to catch invalid .uber.com host name

Not sure this is really important enough to validate with the schema.

There should be some out of the box regex for this

[webron]

Perhaps, but that doesn't mean it's worth it. I have a glorified regex to match mime types too but we decided to drop it altogether. It's not necessarily a real concern.

Closing as out of scope for the specification
