If they block installation of non AppStore apps it will be a big mistake for them. It will just make Linux and open source more popular again and Apple will slowly start loosing the developers and power users, again. Others will eventually follow. Combined with already risky move to ARM, they have to be crazy to go that route. I think digital signatures are purely a security measure, and the dev account requirements are a way to establish some kind of chain of trust to the developer, to prevent bad actors from signing up on the spot and pushing out tons of malware unimpeded.
