The case I know of is in FTP URL:s, where you split on / to find the sequence of CD commands to send, but where each CD command may contain URL encoded slashes (thereby going down several directories in one go, assuming a UNIX like file system).

Hmm, I just realized that it strictly speaking isn't possible to decode the path without splitting it at the same time. Is this true for the other uri parts too?
Otoh, I reckon that the occasions when a user can do a meaningful distinction between a path segment separating "/" and a quoted "/" inside a path segment are extremely rare.
