No, I think the idea of blessing a set of crates (with versions!) is better. The stdlib has a high burden of maintenance, and ideally should only be added to if changes are always backwards compatible. A blessed set is more flexible but still provides a high degree of reliability, unlike the present situation.

This has been tried a few times, and in practice, people prefer the current status quo.

I'm not aware of the attempts, but at least the route of adding more to the stdlib seems even worse, although it may be popular.

Oh yeah, I would agree with that for sure.
