5. You depend on any other package, that provides mkdir-p among other
utilities big enough to be packaged in Guix: Not acceptable.
6. You depend on any other package, that provides just mkdir-p with
maybe a few other utilities, that make Guix devs question whether this
will become the next npm.
7. You write a module, that evals untrusted code from the internet and
point it towards your implementation of mkdir-p.
8. You find existing implementations of mkdir-p insufficient and roll
yet another mkdir-p.
9. You write an accelerated mkdir-p in native code as a shared library.
10. You combine 7 and 9.
...

For what it's worth, I've been hacking on a slightly more complete set
of filesystem utilities over at [1] for the past few days.  It is not
yet complete to the point that I'd consider its inclusion into Guix
upstream, but you might want to try it out and perhaps contribute if
that fits your niche.

In that case, you still recreate npm, just with an additional layer of
indirection.  Obviously Guix developers can not stop you from doing so,
only advise you not to.
