Med] I confirm. This was, for example, discussed here: https://mailarchive.ietf.org/arch/msg/tcpm/TrbMCTywezzzSSjkdntF6EtHl18/

Med] As can be seen in the thread, the intent was: 

"* Consider adding some text to ACK the TCP option space problem. Adding a pointer to EDO as * an example * (without recommending it) of how to extend the space for non-SYNs would be useful."

I think this is adequately captured by the current wording: "... such as [64]".
