There are undoubtedly still problems which need ironed out, many caused (or at least not helped) by eBay's shocking, limited, and inconsistent communication and implementation of this pretty major change.
However, I maintain that things are improving. A quick look through these boards will show you that, firstly, the number of complaints concerning SD has dropped considerably from its earlier high; and secondly, if you actually read these comments, over a third of them are actually complaints about problems with workarounds, many from people who have simply refused to ever use SD. They're whining that they can't get around the rules.
If the workarounds aren't working, that suggests the policy is becoming more secure, and therefore working better, and less open to abuse.
You mention PO's still refusing parcels, down to being unaware of SD's arrangements. This is almost entirely a PO problem (lack of training / communication), and, from the number of posts here, it now seems to be incredibly rare. If the problem is caused by a seller giving eBay wrong information, that's the seller's fault, and is really similar to a seller using a wrongly weighted label in pre-SD days. It happens.
Your most recent posts are still OTT diatribes, with little grounding in reality. SD is not yet in an acceptable state, and it should be, so I agree with you there, but there are a small coterie of individuals who will never accept it, even if it proves to be a roaring success, once bedded in. And that is just plainly illogical.
