Media type parameters optional between semicolons

https://datatracker.ietf.org/doc/html/draft-ietf-httpbis-semantics-11
says:

   media-type = type "/" subtype parameters
   parameters = *( OWS ";" OWS [ parameter ] )

https://datatracker.ietf.org/doc/html/draft-ietf-httpbis-semantics-10
says:

   media-type = type "/" subtype *( OWS ";" OWS parameter )

Is the rationale for making the parameter optional documented?

Where -10 would have allowed:
text/plain;format=flowed
… 11 now allows:
text/plain;;;;format=flowed;;

Very curious.
