It's generally considered less than ideal, but usually not a problem.
As you lose a bit of springiness when the spokes don't brace against each other, rear wheels are sometimes built like that to give snappier acceleration. The straghter path of the spoke increased torsional stiffness a tiny bit. Or out of lazyness, as the build is a tad faster. Can't see any advantage to the pattern on a rim drake front wheel.
The (potential) downside is that the reduced springiness increase the risk of spokes going slack and suffering fatigue.
You can rebuild it interlaced with the same spokes unless the nipples have seized.
