"Sunsetting" inspires the feeling of a new beginning, and positive sentiment than "deprecating". There's a lot of power to be had in being able to influence perceptions with using the right words.

Sunset is not a manned thing, gives me the impressing of God complex.

Besides, I don't think we need a positive feeling here, "deprecate" is perfectly fine, may be a quoted "sunset" is more appropriate here.

It's an established term. That's a fact. It's like calling all people a moron in America who use the term "truck" instead of "lorry".

You're free to insult the intelligence of everyone who doesn't share your extremist minority opinion, though.

Interesting, this do reminds me, I looked it up, it's indeed a US thing, thanks.
