Yes, sadly RM 11708 primarily focuses on HF.
However if you read carefully (or email someone at the ARRL to confirm):
“The Board’s instruction is to seek the deletion of all references to
symbol rate in 97.307(f). That includes (f)(5) and (f)(6). There is
already a bandwidth limit in those subparagraphs.”
So the baud rate part will disappear for HF and above. So that is a good start.
The end result will be just the bandwidth limits.
