With_scope going protected

Was reading up on with_scope and came across this via err.the_blog

Deprecation is a step too far, there are legitimate uses of
with_scope, particularly around encapsulated finds for permissions
models. I just think that there needs to be some serious warnings in
the documentation:

The decision has been rendered as follows: with_scope will go protected
from Rails 2.0. That means you’ll be able to use with_scope in your own
private finders (the only legitimate use I’ve seen), but not in, say,
filters.

Now we just have to find a way to get those deprecation messages in
there when its being called in the public space.

I am still rather a newbie so I am not 100% sure what the implications
are. Does this mean that you will not be able to use (for example)

Model.with_scope( :find => {conditions = “blah” } do
Model.count
end

In your controllers? One reason I do use them in controllers is that it
allows me to add conditions based on things not accessible from the
model (Such as a session variable).

For example

def foo
if session[:bar] == blah
result = “field > 10”
end
end

Model.with_scope( :find => {conditions = foo } do
Model.count
end

Since it is a total pain in the arse to get such data into models
removing with_scope from controllers would be a kick in the nuts (to mix
metaphors).

Can anyone RubyGroupie shed some light on this?

thanks
