Since HDCP has 'broken' (with master key leak), couldn't someone copy a blu-ray bitstream without having to crack any blu-ray protection format?

It wouldn't be the blu-ray bitstream but it would be the decoded digital video bitstream. It would need recompressing although from such a high quality source then generational loss should be fairly minimal.

It also would not get you any interactive elements which for some may be an issue although for others it may be preferable in this way.
