My idea was to make the change explicit first, but module wide (e.g. 
using a pragma or similar), so that there is no immediate breakage at 
all. Only the last stage of the deprecation plan would finally switch 
over the defaults for unannotated modules.

I'll make sure to have a look at the proposal later!
