I suggest just to deprecate this feature. I'm not suggesting to remove it in 
the foreseeable future (at least before 4.0).

I don't think this argument applies here. Two things make the deprecation more 
painless than usual:

1. This feature has never been documented.

2. PyObject_DelAttr() exists from the start (from the time of adding Generic 
Abstract Object Interface).

You have enough time to update your projects, and you can update them 
uniformly for all versions. And may be you will found few weird bugs related 
to misuse of Set* API.
