That doesn't make any sense, and I'm beginning to think you're trolling me with your non-answers.

I am asking you to explain exactly what useful purpose that keeping a notification for a deleted highlighted thread could possibly serve.

Having a notification for an inaccessible thread is not in any way useful for " keep[ing] record of it for future aspects of the wiki" when, in 5 notifications time, your "record" of it will be gone.
 * The notification system is for notifying you, not for keeping a record. There is no reason to "notify" someone of a deleted thread, as clearly an admin is already aware of the problem by virtue of it having been deleted.

Having a notification for an inaccessible thread is not in any way useful "for reporting a problem user with various incidents to staff".
 * What are you going to say to staff, "UserZ posted spam, please refer to my notification area"? It doesn't work that way.
 * The "record" of "various incidents" with "a problem user" is found in Special:DeletedContributions, and Special:Log/delete.
