As to marketing decisions, I think touring bikes should be built to be the best touring bikes, period, and not have components that feel good to potential buyers when they're trying out the bike - people who don't know much about touring.
The touring market is a small one, but people who want a touring bike usually know a lot and have very specific wants - brazeons, long chainstays to prevent heel strike, a ride that's comfortable for lots of miles day after day, a frame that handles a big load and handles well, and a drivetrain that is effective for carrying a big load up a steep, long hill.
If a potential buyer wants something that feels sporty, there are tons of other choices on the showroom floor. If fact, you often can't find a tourer to test ride at all.
