Let's use actual official information. From the SAS website, this is the official SAS Plus offering in Europe:

EUROPE & SCANDINAVIA
* Coffee and tea
* Meal/snack
* WiFi for a fee (available on most flights)
* Fast Track (§)
* SAS Lounge (^)
* Priority boarding
* Pre-book a seat for a fee

§ - Fast Track - SAS Plus passengers have been able to use Fast Track in Scandinavia and Gold Track elsewhere in Europe.

^ - SAS Lounge - we have all agreed that SAS Plus in Europe includes *A lounge access.

And we all know that SAS don't pay for third party lounge access or extra services anywhere there isn't a proper alliance presence - regardless of your travel class. So the assumption has always been *A owned and operated services in Europe. Therefore, true outstations were never included in the discussion and we know that as seasoned travellers

Which brings my back to my point. SAS Plus in Europe is essentially treated as business class today. Let's be clear, SAS isn't paying for better food. It's unlikely they will pay to install dividers. It's unlikely they will immediately retrofit planes to create a section of economy that has more legroom. They have to go with the fleet they have and the services they have - at least in the beginning. That billion dollars they got was allocated a long time ago. They weren't asking for it to have a cushion - they were meeting immediate needs.

I'm not intending to argue for the sake of arguing. It's just when I read what SAS themselves say they have a service offering, compare that to knowing what we know today, and further compare that to the AFKLM European business class offering as listed on their own websites, no one is really clearly articulating what the difference would be between SAS Plus and Business in Europe if they wanted to offer three classes of service. For business, it essentially would come down to:
1) a free middle seat
2) priority check-in
3) priority bag tags
4) maybe free wifi
5) and possibly boarding with Group 1.

In a Europe where the airlines actively steer you towards their apps and automated machines for check-in and boarding passes, therefore de facto nullifying item #2 (and partially #3). Priority bag tags don't negate things like the abysmal waiting time for all baggage at airports CPH and CDG, so there goes item #3. SAS is still wildly inconsistent with boarding, often combining Groups 1 and 2 together, so that's item #5 gone.

I wanna believe But the data points make it hard to do so.
