I don't think obsoleting RFC 8540 will change the reference for details relation form 4960-bis. Then the question is -- is there anything in the RFC 8540 that has not been included in this 4960-bis and that need to leave of it's own? If the answer is NO then we might just obsolete RFC 8540.
All text changes described in RFC 8540 have been incorporated in 4960-bis.
What has not been included is the text motivating each change.
So if you just want to know, how SCTP works, reading 4960-bis is what you want.
If you want to know why something was changed, you might want to consult RFC 8540.
It might give you some background information.

Does that help?
