The distinction is purely academic and it explains the "why" but doesn't change the "what". For all intents and purposes the components have some features inaccessible for [reasons]. Similar to how features licensed in software are still usually present in the shipped libraries. What makes the difference are the price and the licensing terms for unlocking that feature. Chips have been known to have perfectly functioning blocks disabled, or frequency limited not for improved yields but simply because the demand for a lower end SKUs was so high. Unlocking them was a matter of penciling some fuses, flashing a firmware, or simply changing a setting in the BIOS. If anything this kind of licensing opens the door to "hardware piracy" where under the correct conditions you may be able to hack older, or unsupported hardware to gain the full functionality.
