Hello,

After a quick discussion with Jonathan, I open this request as a reminder.

We have a few ncf techniques which are using conditions based on CFEngine classes.

But if the group which is providing the classes is deleted, behaviours of theses techniques will of course change.

When deleting a group, it could be useful to check if group classes are used (sort of constraint) and display an error if so.

Cheers,
