I'm not who you asked, but since i'm preaching about it elsewhere anyway :
input shaping allows one to get rid of mechanical resonances without re-engineering the motion system on a printer. It's pretty unique to klipper -- but it's one of those features that I suspect is brilliant enough to where the other groups who develop such software will probably follow-up with their own variations.
Not sure, I haven't been following Prusa too much lately.
I've spoken to a few people on klipper who are inputing the variables for compensation in directly from an attached accelerometer on the printer frame. That'd be the way i'd want to go rather than taking a pair of calipers to the ringing artifacts on the print itself.
