It's really irrelevant whether anyone is using a feature or not.  If
the feature is documented as being available, it means that removing
it is an incompatible change that can break existing code which
currently conforms to the spec.  If the "feature" is described as the
bug that it is, anything that relies on it is nonconformant.

I do remember seeing some cute tricks (i.e. capable of becoming
idioms) that depend on the leakage.
