Admin Center: Remove user: ACL is still present on my site

I deleted my "Author" user (should I say I turned it off temporarily as he is not really deleted from the DB). But I can still see all its ACL in my edition engines (cf screenshot).

This mix of "user deletion" and "user (un)activation" is quite confusing.

Either we clearly mention everwhere in the UI that a user could only be "(un)activated" (at will). In such a case the user, its properties, ACL, files, etc... still exist but the current user could not login any more (temprarily off). Ideally speaking it should then be displayed in grey.out mode in the admin center and it should be easy to "reactivate" it. ACL and so on should also be "grey out" in the edition engines.

Or the user is deleted. But then it should be permently deleted from the DB. All its preferences, files, ACLs,... should also be deleted too.

I think the second is not possible for Jahia 6.0. So perhaps we should find some workaround based on a "(un)activation" paradigm for the time being and label the wording accordingly.
