I'm not sure what response to what question you expect from spring chairs.
draft-ietf-spring-srv6-network-programming is under WG LC: this is the time for everyone to comment on the document and hopefully improve it. At this stage, I'd rather not influence the discussion.

That been said, since you are insisting

It appears to me that, at minimum, multiple opinions have been expressed on this point, including from Suresh. So, assuming that by "online" you meant "only", the statement "only possible" seems excessive to me.
But I have noted your reading of RFC8200 and your objection, which I believe concern the PSP and USP 'flavors' sections 4.16.1 and 4.16.2
https://tools.ietf.org/html/draft-ietf-spring-srv6-network-programming-05#section-4.16
