It's a consistent notion, but not always common-sense, as evidenced by your (thankfully categorically rare) post.
I am curious about the (thankfully categorically rare) portion of your comment. The impression it leaves me with is that you think this a bad idea.
While I agree it's very rare and not very useful in day to day use, it fits with the DWIM expectation which in my mind would certainly not be a bad thing.
