I second this question.
A workaround:
By the user—
Violate FB ToS, create dummy account and give it admin permissions for your page.
Two possible fixes, one of which has a snowball’s chance:
By Social—
require ‘enable’ on user account to post as FB user
By Facebook for Social Proxy by Mailchimp app—
more granular privacy controls, permissions down to a single page. If I only want the app to mess with one page, and not my personal account, why can’t I do that?
