A valid question and I've pre-attached the flexible and even straight-shot
rigid supply lines whenever possible. However, they do sometimes get in the
way and make a basin wrench more difficult to use, because you can't see
through the supply lines to know if you're turning what you hope you are.

Where it really becomes a problem is with the cabinet size and style. You
don't get many view angles in a 24" cabinet and same goes for cabinets that
have a center stile between the doors. Wall Hung and Pedestal sinks can be
quite tight and having the supply lines on can interfere with a basin wrench's
use, on the handle end. Remember, Supply Valves are usually in the way too
and, commonly, even the drain pipe from the wall or floor.
