Endpoints _are_ capabilities, and general purpose capabilities in L4s
can only be implemented reasonably using endpoints.

Note that from what I heard the L4 people do not have fundamental
objections against a copy operation, on the condition that it is
"necessary".  What is needed to convince them of necessity I don't
know :)
