Of an older version of HDCP. New media can require a higher HDCP version where that bypass isn't possible.

That's certainly possible, but did that actually happen in practice? The downside is obviously that you essentially start selling new Blu-ray discs that don't work on any old Blu-ray players. I feel like I would have heard if that happened. Unless maybe the old players could issue firmware updates?

Yes, see 4k blurays for requiring HDCP 2.2 requiring people to get a new bluray player.
