+1 to "not at all" from me ;-)

There are problems with the deprecation period, but only for  
__ac_permissions__ and meta_types assuming we choose not to deprecate  
'methods'.

If we were naive, we'd change the deprecation warning messages for  
__ac_permissions__ and meta_types in 2.9.4 from "will disappear in  
2.10" to "will disappear in 2.11".

But since we decided (in another offshoot of this thread) that it  
only makes sense to deprecate things in .0 releases, what *should*  
happen is that we should forget about all of this and add "will  
disappear in 2.12" to what will become 2.10.0.
