What if I need to type "too"? More to the point, with longer words it's entirely possible to put the insertion point after that word. The shorter the word is, the harder it is to do, until at some point it is impossible (? maybe I need smaller fingers?). That alternative use case just fades into impossibility (again, maybe) without explanation or guidance.

To be clear: I'm not saying that every choice Apple has made is the opposite of what makes sense. I'm saying that in many cases they could have increased usability, and that overall usability is bad enough that editing is painful, substantially slower than on other platforms (MacOS) and that I think there are at least some use cases they could address, but they haven't.
