(This answer directed also at other answers above :) )

Interesting that so many think that because it is documented on the site, another line of instructions won't help.

Well I think it will. It will be another kind of instruction. Like you said, lots of newbies (at this site at least) probably want a fast answer to their question, and will not read all the (sometimes hard to find) documentation. Heck, I still have a hard time finding certain pieces of information, how can I expect a new guy to do it? Not that I'm very old here, but anyways.

If you were a newbie, and you needed an answer fast, and this text was next to (or right under) the title textfield: "Try to briefly describe your question here. Doing so greatly increases the chance of getting a reply." - possibly even add some no-no examples. What would you do if you wanted an answer?

Ok, so some guys will and do ignore any and all instruction, that is a law of nature. But say that there are 20 posts every day that needs editing, if that is cut into half, that is a huge win imho. Less strain on editors, better outlook of nodes from the start, and less confused newbies that gets unnecessary downvotes or can't find their renamed node.

Above all, I can't for my life figure out why you think it is a bad(?) idea to try it. It is about adding a simple sentence to the HTML. Many small changes can have lots bigger impact than a few big, right?
