Yes.  In particular, the shen draft can be used with TE tunnels as the
backup paths.  This offers a solution in which TE is only involved in
the failure case, which could be much more attractive to customers who
don't want to deal with *all* of their traffic riding on tunnels.

So a complete solution is available in the MPLS WG.  Note that the
not-via address had not been dreamed up when this draft was first
submitted.
