That's basically what I mean. The assumption that baud = bandwidth meant that hams could be penalized for using more efficient digital modes, having a deleterious effect on experimentation with digital modes in bands that were thus restricted. It makes far more sense to limit bandwidth than symbol rate. Who cares how fast your messages are as long as they don't cause interference?
Totally.
Yeah I wasn't sure if you misunderstood or not from your post, but figured my response might help other readers.
More efficient digital modes never used high baud rates, though. Often they used surprisingly low baud rates.
As an example, 4GLTE has a maximum baud rate of 15ksym/s
