> This makes the IR self-contained, which is good, but it also make the interpretation of the IR modal, which isn't great. It means that suddenly the rules of interpretation of what is valid to do or not changes according to this module flag.

I think the original version was better from that perspective - most compiler passes only need to check for one value of the attribute, and only the linker needed to care about the difference between link-unit and public visibility. Do you think we should go back to that design, or do you have a different idea?
