Let’s say just like for example like MacOS. It’s awesome we have so many tools but at the same time lack of some kind of standardization can seem like nothing works and you get overwhelmed. I’m asking for people that want to support Linux or not so tech-savy people.
I’m not that much of an expert but I know display protocols, init system and audio protocol (there are 2 but the new standard supports stuff made for the older one) are standardized.
They are getting closer to this but also I think those projects emerged from being old and unorganized so they want to do it decently.
