The point is, the source color space gotta be linear so the luminance separated from it would be pure, like lab or ycbcr with 2020cl matrix

In that case, I apologize.
The first line of my quotes was ambivalent, but the second one seemed to point me to you saying "Lab is linear", which was obviously a misunderstanding. I'm curious, though: Is a perceptual colorspace actually more suited to resizing than a linear one?
And, as long as the colorspace is linear (or perceptual), why should it matter whether the luminance is extracted into a separate channel or mixed into the other channels? Linear (or perceptual) weighting should just take care of that, shouldn't it?
In any case, the bottom line is: I misunderstood, and I'm sorry
