Is the id friendly or numeric? Not that the return value here is false if the id is definitely not friendly, and nil if it can not be determined. The return value will be:

true - if the id is definitely friendly (i.e., any string with non-numeric characters)
false - if the id is definitely unfriendly (i.e., an Integer, a model instance, etc.)
nil - if it can not be determined (i.e., a numeric string like “206”.)
