3) Why make users change their code to use 'Test2' instead of 'Test', and then to 'Test3' in the future?

That allows users to opt in to the changes.

This is a clear example of the drawbacks of a monolithic boost distribution.

What, exactly, and how it it related to monolithic structure? Opting in for such breaking changes is the only sensible way, IMHO.

The way I see it, it that Test2, Test3 is poor-mans versioning effect by creating new libraries with version numbers added in the name, .. and then shipping all three of them in a boost release? This solution gives very limited version dependency capabilities. When boost moved to git there was an effort to reduce dependencies between libraries. One of wish -by some- was to have a future of boost where individual libraries and their version tagged dependencies would all be separate downloadable. This is not the current situation, of even a goal that’s on the agenda, but I wish it was. It would solve a lot of scalability issues IMO. Having the current monolithic boost releases means that adding version numbers to libraries seems to be the best way forward.
