> It should just work and it should just work well.

That's just magical thinking (thought I totally agree with the sentiment, it should, and Linux should also be better), it doesn't, you're still doing the management, just using a different set of gestures.

For example, knowing about this poor "incredible engineering" I sometimes have to reopen the app in the middle of using another app not to lose my input/position there, especially when I need some basic cooperative behavior like copy paste in multiple steps, where I need to make sure no steps are lost. The primitive iOS system can't guarantee that! And in some instances I'd take the overall sluggishness due to RAM waste over this because then I'd still manage to complete the task, albeit slower, instead of having to redo the work (and in some old apps I could even save intermediate progress to those ancient things called files that Apple despises)

> which is just one tap away from where I was

Except it isn't. If you've scrolled to X% of the document, there is no 1 tap to get back there! And if it took you 5 taps to open that sub-page sub-group it the app setting, then getting from the hope page will take the same 5 taps + some time wasted remembering where you want to go to. And if you lose your input in the input field, same thing, 1 tap won't magically recover it.

And if you're temporarily in a place without (good) network conneciton, you might never get there in any number of taps becaus the page won't load.

Btw, if it's fine to lose user data, than Linux can OOM your apps for you just fine without any extra management on your side. Sure, its current state of app management is not as good as on mobile, it does lack some "engineering" in this regard, though not sure what's so magical about more careful killing of apps
