Hello Dhruv, Thanks for your comment.
When we started writing this draft, our main goal was to propose a mechanism for inter-domain tunnel setup in a coordinated way while remaining operator independent. We chose to re-use as much as possible existing PCEP objects and just proposed to request new IANA code points within existing registries. Of course, this is just a matter of feature encoding for stateful inter-domain. You're right: multiplying the number of PSTs to add inter-domain to each of them isn't a nice way forward. As the I-D is now considered as a WG item, we are open to study any mechanism that fits WG expectations, i.e. we fully agree to create a dedicated PCEP object, TLV or new flag to implement it. I think the best approach, if the draft is adopted, is to publish it as a version -00 and then discuss the suitable mechanism as part of the WG work to produce a version -01 specifying it. Do you agree with this approach?
