Authors,
Looking more closely at the IANA registry, it seems that you have reserved 8
code points for each of the END, END.X and END.T functions. These 8 codepoints
cover all permutations of PSP, USP, and USD.
However, the following permutations make little sense:
* <USD, PSP, USP> and <PSP, USP> because you can only pop the SRH once
* <USD and USP>, because it is identical to <USD>
Also, is there a use-case for USP, alone?

Subject: draft-ietf-spring-srv6-network-programming - Extraneous functions
Folks,
Are there use cases for the following functions:
* 0x001F - END with PSP, USP and USD
* 0x0023 - END.X with PSP, USP and USD
* 0x0027 - END.X with PSP, USP and USD
It seems that if the SRH was removed at the penultimate segment, there is
little sense in removing it again at the ultimate segment.
