Paraphrased (in good fun):

I know that there are already a lot of nodes about this but I couldn't be bothered to look for any of them but that one recent one even though it contained a link to another which itself contained links to several more...

;) Including Re: Automatic Re-ing with numbers (searching). But seriously...

I mentioned this same idea in (tye)Re: Dingbats in node titles: What's your opinion. I particularly like unique titles but, having seen "Re^15:..." just today, I'm not sure even I support the idea.

Though I would like to support "Re^15: ..." as the new default if all the details can be worked out (so I wouldn't suggest one holds one's breath unless one is actually writing code to accomplish it -- for which you can find some of my initial stabs at it via a few choice clicks).

Perhaps "Re^$depth.$sequence: $title"...
