While you're not wrong, there are some cases where these companies limit things because there are under the hood changes.
I remember a few years back, there was a Nvidia feature exclusive to the new cards, and there was a way to enable it on the old cards, and it ran like shit. Like it made whatever the feature was nearly useless. The new cards had dedicated cores for it.
Just like many, many years ago, you could enable double tap to wake on phones that didn't support it, and you'd see a massive battery drain, because the new SoCs had dedicated low power cores to deal with it.
Not saying that's the case here, but there are times where you can enable these features on other devices, but there's almost always a trade off that normal customers would be pissed off about.
