Entire thread gets deleted if the OP deletes their post when there are no replies.
I think the rationale for not deleting the entire thread when there are posts is so that ongoing conversations aren't held to the whims of the OP. Everyone could be actively talking in a thread, but the OP would hold sole power over ending it all anyway by just deleting the thread and none of the other users would have a say.
