We have to keep this as an API, but binding do not need to see it at this point.
Depends on D9296
I would prefer to just keep this or move it outside the .eo file. I mean, we have added that a release back, i do not want to drop it now. Better deprecate it, then we at least do not kill hope in the new API.
Looks okay to me, we just go with the risk that *someone* might still can overwrite it. Its still in the vtable, we could also just make it a plain function that calls the efl_object API. But maybe thats just be being over carefull.
