-> What? ECMP is a kludge to overcome LDP's inability to TE. If

-> perhaps IP header in the middle of an LSP actually defeats 
-> the purpose of MPLS, which was supposed to be have a simple 
-> label lookup in the core.

 Who said that ECMP will be achieved only by hashing labels
 or IP header? I think you are thinking IP ECMP methods
 (RFCs 2991 and 2992) to solve MPLS ECMP. You can do ECMP
 in what ever way a vendor likes - after all, it is for
 load balancing. You can still achieve simple label lookup at
 the core by using appropriate ECMP technique(s).
