I don't think that is sufficient - making something deprecated only 
tells the user that they should not use it in new development.  Not that 
they must rewrite existing code to not use it.  To do that we'd have to 
obsolete it.  (Asside, this is the same as for code - deprecating a 
function only stops it being used in new code.)

I think something needs to be done to the next release that `rubs the 
users nose in it'.
