Just to mention - I like "edit" name :-)

Along with the package recipes that come with Guix, a user can also have
his/her own packages (specified using GUIX_PACKAGE_PATH env var), and
"guix edit my-super-package" opens a user's file with this package.  It
is highly likely that this file is editable, so "guix edit" is a perfect
name in this case I think.  IMO it's a user responsibility to understand
what files can be edited and what cannot.

But I agree that this may be confusing, so maybe we should clarify the
manual to explain in (info "(guix) Invoking guix edit") that store files
must not be edited.

I don't agree.  For example, when you open "/etc/hosts" (or whatever)
file in Emacs, you get a message:

  Note: file is write protected

which indicates that it is opened read-only, but view-mode is not used
by default.  You can enable it manually if you wish.  The same thing
happens with package files.
