When I overhauled the RAND mechanism, I tried to deprecate this use of floating point,

If it's a sarcasm, I'm missing the point.
It *is* stupid.
In general, yes, it is.
Luckily, on a modern system with system-provided randomness to seed the RNG, you never need this call.
There are use cases when one wants to mix/add extra randomness from, e.g., an external source (that, for whatever reasons, is trusted more than what's provided by the system).
