Why not
Speaking from a level of extremely little expertise, it seems to me that the new filament sensor is over engineered. Could not movement be detected by a Hall effect sensor, which could be cheaper.

Ermm.. it's hard to get much cheaper/simpler than a photodiode and IR LED... (which is all an optoswitch really is). A hall sensor would be a heck of a lot more finicky to operate and get readings from.
