long soft brake lines at the calipers can lead to trouble:
getting pinched in the shocks
getting pinched between the steering stops
getting caught in rocks or branches or other road/trail debris
having the short soft lines on top of the knuckles keeps them out of harms way imho.

Stainless lines are not very soft, once installed they pretty much follow the same path when steering. Not very likely to get pinched. Especially when the length is correct.
Any debris that gets to them could also get to the soft lines in a stock set up as well....
But it is a risk I will accept for the ease of moving the caliper out of the way during a trail fix which I had to do last summer...
