I think it is just an accident of history. With the 25 kHz regional 
segmentation of the band in the days of Loran it did not make sense to 
have CW and Fone subdivisions for each region. It was already 
complicated enough just to figure out where you could operate at all. 
Shoot in those days a lot of rigs frequency resolution would have barely 
facilitated dividing the 25 kHz segments in half. When the regional 
frequency and power limits were finally lifted the FCC was not 
interested in putting any effort into writing new regulations for a non 
profit making radio service, any more than they were interested in 
enforcing the existing regulations.
