Ending all school programs that separate children by ability is the most radically egalitarian position possible, even in theory. There is no more extreme position one can take.

Given that, there's nothing else to save the word for. This is the limit; the max. So if radical refers to anything at all, it refers to this.

There are many things I can imagine that are much more radical than this. Everybody has to live the same, wear the same, eat the same, think the same. That's pretty insanely dystopian for sure, but much more egalitarian than barely mixing kids of different ability in the same classroom.
