Yes, the idea is to be able to pass routing information past strict
RFC 822 hosts to a gateway machine that knows that not all machines
are registered with the NIC.  The other common convention of
using bang-path!user@domain rarely works as expected since uucp and
RFC 822 machines like to parse in opposite directions.  Since most
mail handling software is installed on non-gateway machines as well
as gateways, handling %'s as routing operators when no other operator
is present has become common practice even though it has never been
required.
