Couldn't agree more :-) And if that is a key requirement for the next build system it should be explicitly considered as such in future deliberations.
I disagree. I rather like the current system where there is the one monolithic distribution, and you have confidence thanks to the testing that all of those libraries from the same Boost version are going to work together. Its an easier guarantee to uphold for the library author and it is easier to understand for the user.
To break this contract and now say that X needs version so and so of Y, and another version of Z, is I think to introduce needless complexity. I'm not opposed to the idea of modular builds (i.e. get just Boost.HTTPKit and Boost.Buffers without also acquiring Boost.Asio) but I prefer the simplicity of keeping them all at the same version. Update one, update all.
I really need more sleep.. I misread the individual versioning thing. I'm all for modular stuff. But mixing versions is fraught with all kinds of danger. So, yeah..
