The issue is that most users don't understand software on a deep level, and just click "yes" on dialog boxes, etc.
It does make sense to keep the defaults where it prevents most users from harm.
And by experience supporting users, this is not how bad extensions get installed on the system: they're pulled in by malware which gets installed by other means.
This is only going to irate legitimate extension developers, which already have to wait weeks for AMO to review even the most basic change. I've been distributing extensions separately precisely for this reason.
