Or perhaps it could work with a warning message when invoking
an extension command for the first time (similar to what Emacs
does when hitting a key combination that may be unintended).

For example:
$ guix workflow ...
You are about to run an extension to GNU Guix.
Enable this extension for future use? [y/N]

Perhaps this message could include the package from which
the extension originates.
