Proposal:

DELETE_ATTR can be replaced with PUSH_NULL; STORE_ATTR

Since DELETE_ATTR just calls PyObject_DelAttr(v, name) which calls PyObject_SetAttr(v, name, NULL), no other changes are needed to do this.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
