People understand this usually. The problem is that when we try to put the same restrictions upon developers of all users there's going to be a lot of friction with the assumptions in design and UX that make it so great for grandma. Bifurcating iPad OS into a pro v consumer version is probably going to result in worse issues for both groups as well, so building something that can be unlocked once in power user mode seems like the better option longer term. There's speculation about _why_ it's been so hard to get this right and only Apple can definitively say what the reasons are.
