This is certainly interesting, but I'm not quite sure it goes far
enough. In general, when a particular API is being deprecated, there
is generally some form of replacement or alternative that developers
are being pushed towards, and potentially some form of notice that
should be displayed.

Considering that, a Link header might be an interesting possible approach:

Link: </deprecation-notice.html>; rel="sunset"; title="This API will
be sunset on 2015-12-12"; sunset=2015-12-12
