Just last month, I refurbished a few old Windows PCs with 4th and 6th generation Intel CPUs, and while they were pretty much unusable with Windows 10, they still work fine with a current version of Ubuntu.

For what it's worth, if we adopted such a change on Windows, I don't see why we wouldn't also adopt it on Linux—which would preclude using those older chips on Linux as well.
