No, but it is possible and so if it does break, you can repair / replace it. Whether that's affordable is another matter of course, but that's the flaw in the "right to repair" laws popping up now, as unless I'm mistaken it does not mandate reasonably priced replacement parts.
Assuming that the SSD module doesn't have any sort of DRM that prevents anyone but Apple from making them.

They are the same course, imo. That it's been done in this way is typical behaviour we see from them, but expected/unsurprising behaviour does not necessarily make it a justification.
