On more modern pumps that's true: my touring pump is a screw fitting. But they have the crucial technological difference that the screw that secures pump to valve can rotate around the air hose.
I like a decent quality hose pump for use on the road because they keep your hands away from the possibly mucky valve and tyre.
The hose can unscrew a presta valve, although not all presta valves are unscrewable.
I much prefer schrader valves, not least because you can use garage airlines or a passing motorist's 12v pump or foot pump.
