You can sideload, just pay for a developer account and you can sideload whatever you want.

Going further than that effectively removes the point of app review - Facebook/etc will immediately demand that you sideload to bypass the app review and just demand all permissions.

this is not a theoretical problem, Facebook has already been busted for asking users to sideload a version signed with their developer credentials that scrapes up data that apple won't let them collect on the public release. You are basically suggesting that they be allowed to do that officially.
