Deprecation is stronger than that -- it says "we're going to remove this, or we wish we could remove it because it's broken, so you'd better change your code a.s.a.p." -- e.g. Thread.stop(). My interpretation of Martin's comment is that using deprecation for things that aren't actually broken just means that people will live with lots of deprecation warnings in their code for years to come. This could be a perfect case for introducing a weaker alternative to deprecation, saying "here's something better that you should really be using for new code" -- e.g. ArrayList vs. Vector. I remember the Guava team talking about that a lot. Don't know if they ever implemented it.

Surely you have to start somewhere: deprecation is no more than saying
to programmers "Don't use this, use that." And if you were leaning
over someone's shoulder that's what you would say.
