Patches welcome to use Lisp replacements for 'find' and 'grep' on
Windows (with a defcustom that will allow to use the external programs
when they are available).

I don't think this is going to happen, nor that it should happen.
We've had this discussion before, I think more than once, it's time to
let go.
