It is certainly confusing, and has come a few times. It would be more
ideal to copy that file somewhere where it can be edited than trying to
edit the file in the store directly.

It is still useful when building from git, as described in:

  https://guix.gnu.org/en/manual/devel/en/guix.html#Building-from-Git

Then this should work more-or-less as one might expect:

  ./pre-inst-env guix edit PACKAGE
