You mean like http://dlang.org/attribute#deprecated ?

First, if it is a minor increment, it can be proposed as a pull request
for std.concurrency.
If it is a major overhaul, we need to review it more broadly. This is kind
of the problem with just adding things to std, which is why the
std.experimental branch was proposed -- it's so difficult to get bad
design out of the standard library after it has been released. The
deprecation schedule takes years.
