The thing you get by using an OS widget and putting a string in it is that the OS can interact with the string. It can read it out load, translate it, fill it in with a password, look it up in a dictionary, edit it right to left, handle input method editors whose hot keys are in conflict with app doing its own editing, etc…
There’s a reason why the most popular ImGUIs are targeted at game dev tools and in game dev uis and not end user uis
You could potentially make an Immediate mode gui that wrapped a retained gui. arguably that is what react is. From the programmers pov it’s supposed to look like imgui code all the way down. It runs into the issues of having to keep to two representations in sync. The ui represented by react and the actual widgets (html or native) and that’s where all its complications come from
Yes, one argument that I didn't make in the post but that does favor immediate mode is that you can somewhat straightforwardly convert from an immediate mode GUI to retained mode by just introducing your own abstractions. In some sense this makes you more disciplined about the FPS which could be a net win over all.
