I disagree, because then pypy might behave differently on Guix System
vs. foreign distros. A question up for discussion however is whether
it should depend on nss-certs at all.

It would install pip into the same output. Currently our python package
has pip built in and this change would change pypy3 to do the same.
Unfortunately it does not work well on foreign distros, thus I’m leaving
it commented out as future work.
