My brother ran his '72 Roadrunner like that for the same reason. He put the spindles on backwards and then didn't want to take it apart again. He never had problems. But it does make the hose a bit of a pain and puts it into a kind of "S" curve with the potential to rub on things, kink or get jerked.
At the same time, most aftermarket BBK's seem to run them to the rear of the spindle. And my homebrewed C5 caliper setup and Scat Pack setup I am working on run them to the rear.
That said, the best location is definitely to the front for a stock setup. This puts the hoses across the spindle turning axis and means the hose sees much less flex and no risk for kinking or rubbing.
Nice thing about it is, if you ever step up to a Dr Diff kit or similar, you won't have swap the spindles. :)
