[Dhruv]: In the past, there were other MIB extensions -
https://tools.ietf.org/id/draft-zhao-pce-pcep-p2mp-mib-04.txt
https://tools.ietf.org/id/draft-dhody-pce-pcep-pathkey-mib-04.txt

You can find some discussion around them.

It would be good to ask the WG, if there is interest in continuing to
update our MIBs.
If you or other vendors plan to implement this in production
​,​
or if a service provider is asking
​for this MIB extention​
,
​that information ​
would help the WG in making this decision.

[Dhruv]: You can look into Yang, that support stateful PCE anyways. We
welcome comments

[Dhruv]: Got it!
I was thinking that this is a table for only peers/sessions with Stateful
feature.
With augment these parameters are added to *all*.
