It means then probably this way:

1. First ask user if to engage recommending various packages from GNU
ELPA. Program should also represent itself as being gnu-elpa
package. Since I have installed it I did not yet activate it as by
habit I may read package description later. But it activated itself
and so how I would know which package is doing these functions?
Without me remembering that I installed only that package I would now
know what is doing it. User would not be able to turn it off oneself
if there are many packages installed recently.

2. When confirmed, only then to start recommending packages and if not
confirmed then to remember the choice and stop nagging.
