The rationale for that is noted in the list of changes
at the bottom of the spec.
The ABNF of hier-part and relative-URI (Section 3) has been corrected
to allow a relative URI path to be empty. This also allows an
absolute-URI to consist of nothing after the "scheme:", as is present
in practice with the "DAV:" namespace [RFC2518] and the "about:" URI
used by many browser implementations.
