The baud rate limit applies but this means 300 symbol changes per second on each subcarrier. The number of subcarriers and the number of bits per subcarrier is not limited. The ARRL regulation by bandwidth proposal was a better method than the current regulation by content rules but was opposed by too many people.

The fact that they are mentioned does not necessarily imply that they are not intended to fall under the 300 baud restriction.
