I would say that is the definitive scenario in which one would want to use
an external library such as pcgrand.
As others have commented in that thread, locking down implementation
prevents later optimizations. Even introducing a parameter to qualify which
algorithmic sequence you want to use, is a recipe for disaster in terms of
bloating implementations.
At this point one has to ask how much load you want to put on the standards
implementors, when the simplest solution of using an external library
solves this edge case.
