Yeah, true.
Alternatively:  there shall not be both children who receive less than
their natural width and children that receive more than their natural

Anyway, I don't think that the example of "bunch of ellipsiizing
labels" can be generalized to make the
case that the hippo-style algorithm is always better than some linear
distribution scheme.

One thing that I have not seen mentioned in this discussion so far is
the fact that it is ultimatively an implementation detail of the
container how it distributes its allocation to its children. There is
prohibiting a linearly-distributing container and a hippo-style
container from coexisting. Both can use
the same extended layout interface. It would also be possible to make
the distribution algorithm
