The problem with calling it “full stack” (even if it has a widely understood meaning) is that it implicitly puts the people doing the actual lower-level work on a pedestal. It creates the impression that if this is already “full stack,” then things like device drivers, operating systems, or foundational libraries must be some kind of arcane magic reserved only for experts, which they aren’t.

The term “full stack” works fine within its usual context, but when viewed more broadly, it becomes misleading and, in my opinion, problematic.

Or, alternatively, it ignores and devalues the existence of these parts. In both cases, it's a weird "othering" of software below a certain line in the, ahem, full stack.
