I for one welcome our notarizing overlords. Running a terminal command to disable it is a very minor inconvenience for us nerds... in return we'll get fewer tedious house calls from family and friends asking why their computer is doing weird things.
Part of me wishes that Apple would slow down the big innovation for a couple of years and get the entire development team working on bug-fixes and polish.
I attribute it to Apple focusing on iOS and letting their desktop products slide.
