Hmmm. My EE degree is 56 years old, but the term seems quite clear and 
descriptive to an old fart like me!

It's been done in audio systems for at least four decades, where it uses 
motional feedback from the loudspeakers to which the systems were 
carefully matched. The implementation was intended to correct for 
non-linearities in the loudspeakers, which are far greater than in the 
electronics.
