Maybe this is true when manipulating the package definition, but that
doesn't seem to be the case in general. When I run
"./pre-inst-env guix package --show=shogun", for example,
"octave-cli@4.4.1" is listed as a dependency, even though "octave" is
the associated name in shogun's input list.

To be clear, I've changed the string for octave's and octave-cli's
package name in their respective package definitions, but I haven't
changed the string in the input lists of octave-cli's dependent
packages.

I'm inclined to follow convention when it comes to this, and other
packages in input lists seem to omit extensions to the base name of the
package in their assoc-lists. For example, ("gettext", gettext-minimal)
and ("python", python-minimal-wrapper) are common inputs for packages.
