Cool, let's not. Let's not pretend I want to to type that long thing from my phone simply because my os doesn't have a web browser. If you want to, no one's stopping you. I want the basic tools included and always working.
I think you are defining a computer OS as a basic OS -like TRON on a microwave. It is not -it's a multi-GB platform, and a basic tool included in it is not a basic tool you'd expect from a microwave. But these days, some microwaves also include a browser.
Much like airbags are a basic safety feature, but were not 20 years ago. Much like vi was a basic feature. But why include vi, when all you need is ed?
