People absolutely COULD design something better, but if there is a lesson that I have seen replayed across the internet over the last 20 years is that adobe users, only want adobe, they dont want anything else.

They want the shortcuts exactly the same, the screens exactly the same, the outputs exactly the same.

They simply dont accept anything else, it basically needs to be a carbon clone copy to keep them happy, and in that case, why bother writing software, you dont win those users, and there is MANY of them.
