Don't be an idiot. There are some interfaces that we _want_ to extend.
Sysadmins want to type non-ASCII characters when they're editing zone
files, for example, and users want to be able to type those non-ASCII
characters on the ssh command line. If we can support these extensions
at low cost by extending some other interfaces too, great!
