Sadly it looks like at this point that WD has abandoned the SN750. Especially considering that this is an issue that they have identified, and know how to fix, and it is a very small fix, and likely easy to port over.
Typically when small fixes are not ported down the product stack, it often means that product was silently dropped and black listed from any any all further development, where even in cases where a commit can be directly applied with no additional development work, it will still be disallowed.
Sadly it is a very bad look for WD, since this is usually behavior that was previously only exclusive to white label SSDs, and companies like PNY where they took a generic NAND package and controller in the PNY CS900 and other similar models. Then theyt had known firmware issues with the controller where it would gradually corrupt initialization data. The issue was eventually fixed, but they refused to push those updates to their units, thus leaving owners of it at risk of data loss where one day they restart their PC or shut down, and find that their SSD now shows up as something like P0 PS3111 and due to buggy firmware for which there is a fix but the company will not push it out to their users, even though they do not need to do any extra dev work to use push it out to their users.
It is sad to see WD go this way, as it is a major deviation from the rest of the tech industry when it comes to major brands. For example, it is not uncommon to see other major companies port fixes back through an entire product stack. For example, companies like Netgear, will patch major issues on even 13+ year old routers because the similar codebase for the offending module is similar enough for easy porting. While they are not forced or obligated to do it, as some other brands will not do it, it improves good will with the customers and instills confidence in the products by not fully abandoning older products.
