JD:  PCEP is a given.  You are insisting that it needs to be embedded within RSVP-TE and I am merely asking why that is either necessary or desirable.

JD:  As above, the only point of discussion is why you feel it is necessary to embed it within RSVP-TE signaling.  The draft says that this is necessary in environments where PCEP is not available.  Since you are, in fact, using PCEP this argument is clearly nonsensical.

JD:  As an exercise in character development, I will be kind and restrain myself from commenting.

JD:  Just because they are WG documents does not mean they are inviolable.  Ill-advised technical solutions, such as TE metric recording, can be identified and corrected at any point in the process.
