Huh? I don't know how you arrived at that conclusion...

No, the problem is that libraries are distributed, and users use
distributed libraries. In order for these libraries to be modularized,
they have to ship something that allows BMI's to be generated.

Right now, they ship headers. They can't ship BMI's because BMI's are
not portable across compilers or quite possibly even compiler versions.
Shipping raw source will not be an option for non-open-source libraries.

We need an intermediate representation that is *portable*.
