Can I make a suggestion?
Let's consider anything marked 'deprecated' as 'this construct may
disappear in a future release without further warning'. But such a
feature is only removed if there's a clear benefit (speed up in more
common constructs; it gets in the way of implementing a new feature; etc).
A list was posted of all features marked 'deprecated', but it didn't come
with what benefits deleting those features gains. Personally, I don't think
I've any code that's affected if those features get removed. But removal
for the sake of removal isn't something that seems to win us many friends.
Of course, in the grand scheme of things, I doubt there's that much code
that will be effected.
