(1) adding another feature flag is gross; feature flags are not the way we should support "edx.org-only" features moving forward (Ned/Dave have ideas about what we really should do)
(2) this is extremely temporary, will be removed after a short period of time, and I don't want to add a flag that other parts of the codebase start using, when again, this is hacky and not the way we should gate edx.org only features.
