Why successive versions of Stockfish converge towards Lc0?

[Vinvin]

Because a lot of eval patches are written with (losses against) Leela in mind.

Hmmm, interesting, didn't know. How do they do it, a systematic analysis of errors made when playing Lc0? Doesn't seem easy. I think it's easier to do the opposite, to fit Lc0 to SF, either by training on SF games or implementing some tactical abilities of SF.
