. . . so far it as been pretty mutable and centralized, with a still very long and sketchy development of ETH 2.0.

I agree with you on that, and that it's questionable as to whether it should be included or not. I turned a blind eye precisely for the same reasons you give for holding some. Personally, I'm not involved in ETH, but since most would argue it's legit, for the sake of this analysis, I included it. There's still the 2.0 hope too. Time will tell.
