I agree with this. Notably the "not removing libraries from Boost 1.x" part.

We have users that upgrade Boost versions regularly that:
- Have only one Boost install across the organization, and
- Have projects that depend on old libraries like Boost.MPL as well as new
libraries like Boost.Json

And enough of them that I would prefer to keep supporting them in Boost 1.x
as much as possible.
