Typically there's always been an implicit "unless the security risk is wild".

Even though it's in-fashion to hate them, Microsoft has been pretty amazing at keeping compatibility. This one is pretty painful, but I really don't think they're doing it just to fuck with people or force you onto Windows 11 (as some people seem to think).

Windows 10 2004 itself has been out of support for 4 years. At some point, they have to drop code that's maintaining compatibility with obsoleted older version of Windows.
