Yes, it's very normal. You don't hear it because, in the US there is no need to request the higher speed if you need it. MD-11s at max TOGW often have clean speeds at 280 or higher. Even 767 freighters sometimes need greater than 250. However, outside the US there is no relief unless requested specifically from ATC.
