Comment (by Adam Johnson):

 > If someone registers converters with the same name as builtin
 converters, they will get what they deserve. What if they do it on
 purpose?

 Even if done on purpose, users can break URLs in other parts of their
 project or packages unwittingly. If you need a modified `int` converter,
 for example, there’s little harm in requiring it to have a different name,
 but potential harm in allowing silent replacement.
