It’s clearly not there yet, no thanks to many years of Apple insisting the iPad must do all things entirely differently from the Mac
Precise input, a file manager, external storage, etc. weren’t a thing for the first half of the iPad’s existence. They’re paying for it now
They’ve got the chance now to set up the tooling to make one great app that adapts well to all of these platforms, and it will take massive investment
But it all flows through iPadOS (by way of, of course, the iPhone). So yeah, I don’t think it’s going away anytime soon
