Yes, they seem to be explicitly rejecting the ARRL's request for a 2.8 kHz bandwidth limit, allowing a single transmission to be as wide as desired. In theory, one could fill the entire CW/data portion of a band with a single transmission. Sure, one could easily argue that that's not "good amateur practice", but where is the limit? If the FCC says that 2.8 kHz is too narrow to set the limit, then is 10 kHz OK? How about 25 kHz? That would be half of the 30m band, or a huge fraction of the data portion of the 17m band. It's hard for us to listen and avoid interference if we have widely varying bandwidths. I really think 3 kHz is wide enough, but if it isn't, at least let the rules keep the wider transmissions separated from the CW portions of the bands.
