You didn't get any responses AFAICT. That doesn't mean nobody is
interested -- perhaps your proposal is simply too general? Do you feel
up to making some more specific recommendations about the exact list
of functions to add? It's easier to criticize a concrete proposal. Do
you feel up to producing a patch that just adds the incomplete beta
