Why are the wipers so low quality?

It's almost like they're static lines that are moving somehow, other PMDG aircraft have better wipers with smooth(ish) motion, and other addons have even better wipers with detailing, at least make the animation smooth, not make it feel like an 8 bit game?

I haven't noticed, but if I had to guess, it would be something to do with performance.

Moving/animating a complex 3D model around, is a lot harder and taxing on the system, than a simpler model. Especially considering all the other systems, calculations and moving parts, which also has to be animated on such a complex piece of machinery...
