One correction, the A330 limits rudder travel to 4 degrees above 350 CAS. If I am incorrect, someone please say so. I am not rated on type.
To your point of protections being offered, I agree there is an understanding that the rudder could be needed at cruising speeds and there is reason for limitations, but the cases for this need are rare cases indeed.
Yaw dampers take on most of the task of yaw control at cruise. When these units go offline, it is best not to try to even out a yaw oscillation since one will almost always be behind the curve.
The only other time I would think the use of that control surface is called for at speed would be during an unusual attitude recovery maneuver. In this case, travel limiters or force feedback systems are there more to prevent dangerous pilot-induced yaw than to protect the vertical stabilizer.
