That might be part of the confusion.  MPLS was solutionware searching for
problems for so many years that it has been kind of hard to keep current
with exactly what problems it was supposed to be good for.  It has since
actually found a few problems which people seem willing to attempt to solve
with it, but as far as I know none of these require the functionality you
are describing for whatever problem it is which you think MPLS is supposed
to be solving.

I hence think the answer at this point is exclusively "yes", it has nothing
to do with e2e.
