Who cares about 'advanced' users? There's so many less of them than normal users. Do normal users actually pick devices based on being able to side-load apps?

Who cares about 'advanced' users? There's so many less of them than normal users. Do normal users actually pick devices based on being able to side-load apps? If yes, then I'd eventually expect to see it in iOS. If no, then I'd not expect to see it. For what little it's worth, I think the answer is 'no', but that's based purely on my personal experience and could well be wrong.
