Hits the advertised specs so it’s all good
If you’re reliant on a non-published spec of a product and the manufacturer changes the ingredients such that they are still meeting their published specs then you’re taking a risk, even between batches of the same model. I think Sammy’s actions are almost totally fine, but.
It’s a royal pain for folk trying to maintain homogeneous infrastructure or replace like-for-like. So, put an additional number at the end of the model number, how hard can that be (SAP be damned).

Still hits all the searches, the marketing material is all still good, avoids this sort of ‘are they trying to dupe their customers’ vibe.
