It would, and I'd be happy to do it while I'm on vacation next month. 
Can you submit a change request?

More generally, what would the Powers That Be think of my adding various 
special functions (like probit, inverse probit, Bessel functions, gamma, 
log gamma, etc.) to racket/math? I've already written quite a few in 
Typed Racket for my own use.

Come to think of it, racket/math is a great candidate for being written 
in Typed Racket but the racket collection has to be compiled before 
typed-racket. Is there a way around that?
