Necessity. When most of the software you use is reliant on Windows it’s hard to make Linux your daily driver. That being said, the changes needed to make it worth it are already done in limited contexts. Steam deck is pure Linux, the user interface and everything is implemented in a way that the user does not have to deal with the complexity, but the underlying mechanisms for doing wonky shit is still there if you want to mess with it. It’s kinda the best of both worlds in that sense.
If we wanted a desktop experience to replicate that, you would just have to do the exact same thing. Abstract the user experience such that the layperson does not need to engage with the complicated bits, but leave them there for those that do want them. And arguably that is being done with some distros, but it’s just not quite there yet.
