I think it's reasonable to assume that JDK 25 is supported on Windows 7 and later. However, it would be good to add a notice in JBS stating that it should not be backported.

FYI Microsoft still support some updates of Windows 7 .. if you pay them enough, but they do NOT support
the earliest updates of Windows 10.
So Windows 7 is more relevant today than early Windows 10 versions.
Looking at adoption numbers might tell you a similar story.
JDK 25 will ship before Windows 10 leaves mainline support - and it'll also have a long tail on the latest versions.
But Windows Vista isn't something I care about for JDK 25, although "not crashing" would be nice :-)

And yes, the backporting was the big issue with that other fix. Plus that the impact was huge.
