And I wish more frame manufacturers would adopt the gearbox model or even better - Shimano or SRAM release their own systems and hopefully fix some of the annoyances of Pinion.
Buuuuut these days everyone is playing the weight game... like it matters that much.
And honestly, having an extra weight, but low and centered is not that bad - it allows for better working suspension and super planted, stable and balanced bike. Also, no derailleur to rip off, super low maintenance, perfect chain-line all the time, shifting without pedaling, you don't hassle about mud, cleaning, oiling, etc.
Overall it's a more sustainable system with longer-lasting components, which leads to less waste. It simply needs some refinement.
