You are listing edge cases. Nobody cares.

You buy a laptop, you install Linux and it goes. That's the bar for mainstream usage.

If you have an older computer that no longer gets MS or AMD updates it's cool that Linux can be installed on it and be marginally safer, but it's disingenuous to not acknowledge that in that scenario unsupported Windows still works, by definition. For people on older hardware their older hardware is already working.

Linux can, at best, have a lighter footprint (and be less full of decades of leftover garbage) and make some forward compatibility available on very old devices, but it's not unlocking hardware that wasn't working because it didn't have drivers. Windows does do that in general, and especially for newer or niche hardware. Lying to ourselves about this is not doing anybody any favours.
