I would never have guessed. You are just essentially rehashing my prior statement though.
And yes. There has been improvements.

Then you agree ,Vega and Navi are different. Even thou we know that they are using a similar GCN but have different quality and optimization, let alone die size.

"Probably" is not something I can adhere to.
It is likely a semi-custom GCN base with forward-like navi features.
Maybe just maybe... AMD has sorted out their Primitive Shaders and Draw Stream Binning Rasterizer in Navi? :P
Graphics Core Next is modular remember... AMD can take a Graphics Core Next layout and just update certain blocks on the chip whilst leaving the rest identical.

They could but what for, the primary function of early SDK is to test the possibility outcome of performance close to the target. If they tried to build a modified vega costume then it will take times just for the prototype. I bet they prefer using pure Vega chip for now.
That's possible if SONY in hurry and run with time, but there is no indication that SONY want to release PS5 soon. They prefer waiting for the next GCN architecture to come.

There is more to chip costs than just size.
Patterning, Leakage, Spare-Area... You name it.
And contrary to popular belief... Just shrinking a chip doesn't always mean it will be cheaper to produce, sometimes the contrary can remain true.

agree
But for now it still another decade to worry for that, probably after we achieved 5 nm?

"Availability" is one of the design principles of GCN to begin with. |
No , I am talking about the benefit of GCN that they mentioned in the GPU road map, which is scalability

Not only that... But in the consoles things like power delivery, power states, video decode/encode, caches, memory controllers and various other bits and pieces can be consolidated/reduced.

Agree you name it, i just simplified it
