Sorry for the confusion. Ad-hoc should be retained with the same effect, so
that we do not break existing scripts.
Renamin the option would be ok. It even makes sense to me.

That could be done. The problem is caused by uses of guix environment that
does not use any of these options. Those mean different things after the
change.

Ok.

We could recommend simply to use something like:
GUIX_ENVIRONMENT_DEPRECATED=0 guix environment ...
Instead in existing scripts that are fixed to use the new syntax. This
indeed looks like a better solution, and it is less of a maintenance
burden. Good idea.

Summarizing:
Introduce the environment variable.
For fixed scripts recommend unsetting the environment variable.
That looks like a better plan. Thanks for your insights.
Best regards,
