Take Trek for example. The only thing they offer in non-disk brakes is (1) their completely bottom of the line 820 MTB (2) as an option on their Project One Madones. Even their 520 touring bike is now disk.
Changing their 520 touring bike to discs was a smart move. I have read more than a few touring reports where after riding many day in the rain, their rims wore thin and broke. Riding in the rain some days comes with touring, and rain and fine grit get on the rims and rim brake pads use it as a grinding compound to wear down the rims.
