Indeed. There is no MUST there. That is precisely what section 4.1 of
RFC8200 says:

4.1 <https://tools.ietf.org/html/rfc8200#section-4.1>.  Extension Header Order

 When more than one extension header is used in the same packet, it is

*  recommended *that those headers appear in the following order:

Does this document (or your comment) create a

If by "this document" you mean draft-ali-6man-spring-srv6-oam then no - I
do not see any text there which would even attempt to enforce any EH
ordering.

As far as creating MANDATORY ordering "by a comment" that must be pretty
new extension to the IETF process :)

Best,
R.
