@Mark,
I happen to agree with each and everyone of your points, however, my point is that if you remove the editor and let the plugins and themes upload and update functionality, then that is pointless.

This brings us to, should we also remove those ? Pretty easy for me to say "Good Luck with That!". Reasons ? I will give only two:
1- Users and developers are used to it and they will eat you alive before they let you do that.
2- Do that and "Ease of Use" will go to 0.1% and you will have ended WordPress overnight, Period.

So to wrap this up, your arguments about the editor also apply to this functionality and since there is no way in heaven nor in hell to enforce them here, they become baseless.
