I'd like to suggest that we either document the "right way" to extend the information to support new URL schemes, and possibly add a function as the way to do that. Having to update a whole set of lists from outside the module seems a poor and error-prone way to do this.

It sounds like appending to the list was the right way up until now. That is, extending the list of protocols is a reasonable feature and using a list with a non-underscore name provided one obvious was to do that.
