The activity during cw contests doesn't seem such a problem.  There is 
always ample room above 1900 even during the heaviest cw activity.  I 
sometimes hear routine cw activity near 2000 kHz to escape the contest QRM.  
But the opposite is not true during SSB contests.  They completely wipe out 
all cw activity.

It would seem so simple for CQ, ARRL and whoever else may sponsor the 
contests to put certain frequency ranges off limits (for example no SSB 
below 1840 kHz), and declare that any participant who fails to adhere to the 
plan will be disqualified.
