I don't think that is unfair. It’s perfectly acceptable to be a 3x developer.
What bothers me is the people that are happy to be a <1 developer. Or even a <0 developer, whose benefit to the team is net negative.

We can't all be above average. So we are either all 1 developper, or some of us are bound to be less.
If it ever gets to the point where everyone is floating somewhere between 0.9 and 1.1, I’ll revise my statement.
When they're spending all their working hours on one topic they're taking a huge personal sacrifice which is invisible to their employer while at the same time raising the expectations towards their colleagues. If there's for example two such maniacs in a team, the rest can say goodbye to promotions and raises even if they're actually just as good but don't sacrifice their life at the altar of programming.
