I have recently started with Old School, a fun a freshing distraction from 60-card Pauper and EDH! Would WotC consider an errata for Chaos Orb and Falling Star to align with the rules used in old school? This would be completely harmless, as no other formats use them (and the “house rules” are better balanced besides). But it would be a wonderful gesture and nod to the community.

We don't tend to functionally errata cards for a single format. At most, we might ban a card in that specific format.
