Yingzhen,
As you mention, Section 11 title is "*_/Advantages/_* ..." and not
"mandatory", "must", "required",..., etc. Section 11 was moved to an
appendix based on comments, not based on a change in the stance of the
draft about the repair path being congruent to post-convergence or not
As for post-convergence being mandatory, it was NEVER mentioned since
version 13 (and even since version -00) of the draft that
post-convergence is a required, mandatory, or must-have.
I do not know where the idea of post-convergence mandate came from !!
The only remaining items was the two DISCUSS items and they were both
addressed in latest version
As an author, IMO the draft is ready for publication

Hi all,
Since the draft-ietf-rtgwg-segment-routing-ti-lfa version 13 was
submitted to the IESG for publication in Feb this year, it has gone
through several iterations to address review comments.
We'd like to bring the WG's attention that it is no longer a mandatory
requirement to follow the post-convergence path. The section 11 in
version 13 (Advantages of using the expected post-convergence path
during FRR) is now in Appendix A. Ahmed mentioned during his
presentation at IETF121 that this change was due to hardware
limitations (recording: https://www.youtube.com/watch?v=6qVpJsG9nO4),
but this is not included in the draft. Whether it is important to
follow the post-convergence path is not clearly stated in the draft,
or under what circumstances the post-convergence path is recommended
and should be followed.
We'd like to get the WG's opinion about the change. Please note that
currently the draft is Standards Track. Whether it should be kept as
Standards Track or moved to Informational should also be considered.
Please review the latest version of the document and send your
comments to the list before December 14th, especially if you're not in
agreement with this change or you think it should be moved to
Informational.
Thanks,
Jeff and Yingzhen (RTGWG co-chairs)
