I’ll try to add more later, but it is believed that multiple times, a bug in some random API has allowed for the “hidden” Apple account to be revealed because they resolve hide my emails to the original internally. Using a separate namespace would be the universal fix.

This doesn't follow. The bounce message used to (effectively) say,
reply> abc@icloud.com forwards to real@gmail.com
If they switched the new domain and did nothing else, it would say:
> abc@privaterelay.appleid.com forwards to real@gmail.com
That's no better. Fixing that privacy leak is unrelated to whatever the destination domain is.
No, using a different domain makes it easy to across the board add a rule: don’t treat as Apple ID.

replyIf you dig more you could find the bug, but AFAIK it was that if you sent a large attachment, the bounce email would contain your real address.
