Well, this is And you don't have to prove

OK, if you say so, but in general theoretical (or formal)
proofs rank much higher than "try and see" experiments which
only show that the observed outcome is one possibility.

Often if something is possible that is well-known since it has
been tested on the field, for fun or pleasure, long before it
reaches the world of PhD students ...

It is, if there is no alternative in Emacs that is at the same

Indeed, if the Dired ones are worse than the shell tools in areas
that are critical.

I think it is possible but as long as no one does it doesn't
matter what anyone thinks. But if head(1) and pwgen(1) can do
it from C Emacs should be able to do it from C as well
(built-in, a so-called Lisp primitive), or from a
dynamic module, also in C ...
