Bands with a 300 baud rate limitation eliminated by this order are the 160 meter band; 80 meter band; 40 meter band segments 7.000–7.100 MHz and 7.100–7.125 MHz; 30 meter band; 20 meter band segment 14.00–14.15 MHz; 17 meter band segment 18.068–18.110 MHz; 15 meter band segment 21.0–21.2 MHz; and 12 meter band segment 24.89–24.93 MHz. The 10 meter band segment 28.0–28.3 MHz has a 1200 baud rate limitation, which is also lifted.

“Instead, the commission establishes a 2.8 kHz bandwidth limitation in the applicable amateur radio bands,” it said.

And a hard bandwidth limit really does limit total data rate, the symbol rate limit didn’t - exactly the opposite effect that the loud anti-baudrate-limit people wanted

An interesting angle I hadn't thought of. I suppose it's hard not to equate bits and symbols. However, I'm not aware of any digital modes that need so much bandwidth.
