They're often used unflexed these days. They've become an extension of bars.
See eg. most diesel train sets, Emerald Night, 10199, 7862
And that's not to mention the number of MOCs that use them as bars. Or would if they could, mostly they overlap lightsabers.
And having the fixed lengths makes instruction generating easier.
For flexed versions we'll always need something more sophisticated but that's no reason to hold up the straight versions.
