If the draft intents to provide a mapping based Segment Routing solution, there are SR-MPLS, SR-MPLS over IP exist, and there are implementations that work very well; seems no need to define a new one;

If the draft intents to provide a header compression solution to SRv6, there are several candidate solutions under discussion; seems it's premature to consider just adopting one and ignoring others;

If the draft intents to be one of the building blocks of a new competing IPv6 based Segment Routing solution, given the community has been working on SRv6 for so many years, it needs to prove that the new solution has much better merits than SRv6;

So, based on the above, I do not support the adoption at this moment. 

Best regards,
