When people are bike shedding, they aren't doing it to waste time, they think that they are adding value because of `list of bad results of wrong colour here`.
So here's my question to you: could you be wrong about this having "concrete effects on adoption"? And if you are wrong, is this just bike shedding?
And to continue the bike shed metaphor, it's about people ignoring nuclear power plant design whose worst case scenario is nuclear meltdown. For CockroachDB 1.0, what's the equivalent, data loss? So are you discussing something technically trivial (colour is easy to understand) over the design (technically complex) that would prevent data loss? If the answer is yes, aren't you bike shedding like a champion?
tl;dr Bike shedders don't know they're bike shedding and think the discussion is very important.
