Penn Early Decision -- now RESTRICTIVE Early Decision?

Penn was criticized for accepting over half their class during the ED round for the last few years. They may be planning to take less this year. I highly doubt they are worried about the few students who break the ED contract. Penn will probably make some sort of announcement about this new policy - most students/guidance counselors haven’t even heard about it yet.I’m wondering if the common app is going to enforce it - like they do if someone tries to apply to two schools ED. Will the common app be able to prevent an EA application from a Penn ED applicant? (Not that I’m suggesting students ignore the policy - I"m absolutely not advocating that - just wondering how it will be enforced.
