It's why we use the term "object capabilities" (a term first used only recently), to make it clear that we're not talking about special hardware registers or some other form of capabilities.

IIRC, the olde Intel 432 used hardware capability registers to
implement an object-capability instruction set architecture. (Yes, a
bad architecture, but that's besides the point)

I think the object-capabilities vs other models is a semantic
distinction, and is largely orthogonal to implementation substrate.
