Can some of the moderators revive (undelete) this question (my own) and it's answers? I was more than sure that it is completely useless and voted to close or delete it. But, other users suggests in comments, that even this kind of questions should bring some value to the community.
Unfortunately, I was too slow and read these comments after question was deleted by moderator. As per this answer, I can see that questions and answer deleted by moderators can be revived only by them.
