Ability to make thread deletion reasons publicly visible

[JJ1]

Currently, when a non-moderator opens the URL to a deleted thread, the generic "this thread could not be found" message appears.
I suggest giving moderators the ability to make the deletion reason visible to non-moderators for improved transparency, similar to how it is on MediaWiki (a wiki engine).
This would remove the need for members to ask why a thread was deleted, and would serve as a reminder of the rules.

Possible example: Instead of "The requested thread could not be found", show "This thread has been deleted for the following reason: ...".

Love this idea

I honestly want this for all deleted content. Sometimes deleting a post is a necessity, but doing so can make a whole resulting discussion nonsensical. I'd love the ability to leave a "Post Deleted Due To [Reason]" message in-line in a thread where the original post was too.
