Comment(by zooko):

 Oh, so this suggests a further refinement: child links that have caps that
 begin with one of our defined prefixes such as {{{URI:CHK:}}} but which
 are not well-formed according to {{{uri.from_string()}}} will ''not'' be
 treated as child links potentially-from-the-future but instead as bad
 child links, the same as child links which try to provide mutable access
 to you when they are in a mutable directory.
