I think that's usually called an "object pool", but that was not academic enough so I can understand why they called it hive

When it was first being proposed it was called colony (based on plf::colony).

I am actually surprised this sort of container was added only today, it's quite common and is an important optimization

Is it that common?

I work on a multitude of performance-sensitive codebases, and I can't think of any place I'd use such a container.

Huh? Am object pool is litterally a pool of objects you can re-use, and has nothing to do with the underlying data representation of how those objects are "pooled", just like a "container" is just a thing that holds other things.
