The short summary seems to be that there aren't any practical ways of supporting TIFF files larger than 4GB without altering the format in a way that makes it fundamentally incompatible with existing libraries and applications.

That is correct.

Suggested approaches include the addition of a new 64bit offset format (essentially a TIFF64 format that wouldn't work with any existing applications)

What suggested approaches?

I don't recall receiving any such suggestions. And since I'm the one currently maintaining the TIFF spec.......
