I’m not using “trivial” as a measure of ease of back-end implementation, but rather of how it actually changes user experience and productivity. There is no limit to how hard it can become to implement trivial changes behind the scenes; it would be silly to ignore or downplay the ossification of desktop OS capability just because software developers continue to expend more and more effort to make smaller and smaller improvements. My reading of your comment is that you aren’t actually interested in thinking about non-trivial changes here. “Didn’t you know people have tried eliminating folder systems before? It’s hard and hasn’t succeeded yet” is obvious and does not seriously engage with the possibility. (“Didn’t you know people have been attempting to make stylus input work for decades without success?”) Likewise, the fact that web apps can be disguised as native apps is not the same thing as eliminating the distinction at the user level, and I don’t think you would have conflated these if you were really interested in it. So I don’t think it will be productive to continue this conversation.
