PhoneUS Method isn't accurate

Subject of the issue

PhoneUS Method is supposed to validate phone numbers to ensure they follow the 9 digit protocol. Phone numbers cannot be all 1's or a series of consecutive numbers such as 1234567. This is enough of a deterrent. However, yesterday, I came across a form, that when filled with the value 555 555 5555, validated as correct. Of course, this form IS incorrect.

Your environment

1.16.0 Chrome 63.0.3239.132

Steps to reproduce

Visit https://jsfiddle.net/ssguf2jy/ Fill in the phone number as 555 555 5555

Expected behaviour

An error should appear to the right of the field saying "x Please specify a valid phone number"

Actual behaviour

A check mark appears to the right of the field that denotes valid data.
