this is probably going to be my last reply to you, because it seems you dont really understand how this works. to put it very simply:
when multiple SKUs had no difference but storage space, they were more hurtful than harmful when it came to things like manufacturing, shipping, product orders, marketing, product placement, customer service, customer support, logistics etc. All things that go in to the process of selling a new console.
Now take into account you are discussing multiple SKUs that have actual different features between consoles and different user experiences. Youre multiplying everything i said above by a large number. Only increasing the hassle. There was a reason why there was only 1 type of PS4 and XB1 at launch.
If you think any of the platform holders will launch multiple SKUs at launch, even just a 1TB & 2TB version, that is mistaken. Now add to that you think there will be things like a mid-grade cheap version, a super powerful overpriced version, and a bare bones streaming console for dirt cheap? Like i said on your original post, whatever planet you envision this happening on, it's not earth. There will be *one* PS5, and *one* Xbox Scarlet.
This will ensure that all launch logistics are aligned, marketing is aligned, and the consumer base is aligned. Mid-gen refreshes dont have to worry about this because they have their own set of these logistics. So comparing them to multiple launch SKUs makes zero sense.
