Not sure what you are referring to. There are no knobs involved in the things I mentioned (aside from the one to enable the experiment, but that's just temporary until the experiment completes - one way or the other).
The knobs are the values that can be given to GOGC environment variable.
Also I kind of foresee they will discover there are reasons why multiple GC algorithms are desired, and used in other programming ecosystems, thus the older one might stay anyway.
Your previous message was referring to Go "getting" knobs, but GOGC has always been there.
The older GC algorithm won't stay, IIRC the plan is for it to be removed in 1.27 (it's kept for now just to give a fallback in case of bugs in the first release).
