not really "killing the benefits"... just not fully realizing them..
just like a 26" 243 or 6.5CM will shoot flatter, have less wind deflection and recoil than a 26" 308... everything else being equal
so will a 20", just at a slightly lower percentage...
without doing any real math, say in 26", a 243 is 25% better, and a 6.5CM is 18% better... in 20" they may only be 15% and 10% better respectively, but they are still better....
and reduced recoil (felt) will improve, because at 20", we're typically talking about lighter rifles.
