When you press delete on your own answer a confirmation dialog pops up, asking "Vote to delete this post?". I find that confusing, because you are not voting, you are really deleting it. It should read "Delete this post?" instead.
This has been declined for no good reason. See
Jeff indicates in the post linked by Vinko that fixing this would be far more effort than it's worth. I don't know how things are with other dev teams, but that's their judgment call and to me it is sufficient reason to decline to fix the bug.
The best you could ask for is
status-deferred, implying that it will get fixed when other higher-priority things are addressed. However, IMHO,
status-declined is more honest, because the chances of this actually getting fixed are really small.
