Right. I don't mean to suggest that it's only boosts problem. It's a
problem in the assumptions that all these packages make. As more and
more projects are built by composition of more and more libraries (a
good thing!) It becomes apparent that the original "naive notion"
breaks down. That's what we're seeing.

I.e. it's things like vcpkg, conan, cget,
> nix, and many more that use the "modular" level dependency view.
