I don't consider this being a breaking change, but we need to define a
deprecation period for this kind of features. For example we declare it a
deprecated feature now, which means we'd officially (to be documented)
support it for 2 more release cycles.
Obviously this is something that could apply to any other feature we'd
like to deprecate.
