Right.  For the full set of extensibility, today we’d probably say:

tcp-header = {seq: uint, 
              ack: uint, 
              * $$tcp-option,
              * label .feature "Unrecognized TCP Header Extension" => any
             }

label = text

So the options that are known to the implementation land in the socket tcp-option, and the other ones land in the feature-tagged catch-all.

Grüße, Carsten
