With a reasonable load connected? No way!

Perhaps you are confusing an unwanted self-resonance in a roller 
with the tuner "loading into itself".

The reduction in efficiency is so gradual and slight no one would 
ever notice. Long before the power drops substantially, a 
component will fail. Unless you are running less than a few hundred 
watts into a tuner capable of a few kilowatts when properly tuned. 

People just need to learn to use the maximum possible 
capacitance that allows a match in a T network. That really is 
pretty simple.
