Option to support more than 5 countries

[thomaschuffed]

I am supporting about two dozen countries since those are the places we can handle payments.

I currently have to allow users to type in any country and then receive a validation error when they blur the field since I cannot limit the countries to more than 5.

I am curious if there is a reason to throttle this to just 5, and is there a way to turn this off and allow more countries?
