I don't think we've ever made such guarantees for the `rvs()` distribution
methods. In any case, moving from the inefficient default inversion to a
reasonably efficient sampling algorithm would win the argument over
stability. Tweaking an existing efficient algorithm, maybe you could argue
more in favor of stability, but as you point out, this is a GO/NO-GO kind
of improvement.
