I suggest this section be removed from this version until the community reaches rough consensus.
Further, the example for PSP in the companion doc srv6-net-pgm-illustration is wrong. PSP is used for END.DT4 in the companion doc while flavors are only defined for END, END.X and END.T in srv6-network-programming.

Best Regards,
Zhenqiang Li

Authors,

Lacking the B.INSERT and T.INSERT functions, can you describe a use-case for the PSP and USP flavors of the END, END.X and END.T functions?
