If you're allocated a "full" TCB based on only an unconfirmed SYN
then you probably would not mind allocating one that is UTO capable.

So I don't really see any harm in prohibiting it from the SYN, unless
it's presence there is needed to keep connection tracking middleboxes
happy or somesuch. The passive endpoint certainly does not need it
to be in the SYN. Any timeouts before the connection is fully
established
are going to have their own logic anyway.
