Xtrac gearboxes used in S2000 have a centre differential as an option. The reason why it’s not used I think is weight saving. The lack of a centre differential doesn’t ruin the cars car's driveability that much that it would be worth using.“Don’t eat the yellow snow” Frank Zappa

I think it's not because of weight. In my opinion it's more likely because of power loses which are rather important with less powerful normally aspirated engines of S2000 cars. My estimation is that it can save 10-15 Hp.
The other thing is that mechanical center differential is not that useful for car handling as active one.Stupid is as stupid does. Forrest Gump

That must be the case.
In a Mitsubishi evo 9 dyno graph the max power from the engine was 202,7 kW (276 PS) and the max power from the wheels 170 kW (231 PS). The difference is 45 PS which 16 % of the power from the engine.
Assuming the losses in all three differentials are the same, with one differential less the power on the wheels would increase by 15 PS.
Maybe I know remember why they don’t use a centre differential.“Don’t eat the yellow snow” Frank Zappa
