It sucks in a way, but so would adding yet another new slot just for
(at present, and possibly forever) making gc and generators play nicer
together.  "Practicality beats purity" here.

It won't be me:  I wasn't even able to make enough time to understand
the new generator features at the Python level, let alone the
implementation.  At PyCon, when Guido showed his slide with a new
yield-as-expression example, for the rest of his talk I was wondering
what the heck the example meant <0.3 wink>.
