Many touring bikes just are not set up to accommodate them.
Many people stay with what they have.
There isn't much demand for touring bikes period (compared with other segments of the bike market), and there is even less demand for touring bikes with disc brakes (for various reasons, some of which are mentioned above).
Sheldon Brown has said that eventually discs will overcome and predominate.
It takes some years though.
