I'm afraid the gated blocks depend on additional identifiers – _XSAVE_ARM64_SVE_HEADER_, _XSTATE_MASK_ARM64_SVE_, and _XSTATE_ARM64_SVE_. They also reference ⁠[_LocateXStateFeature_](https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-locatexstatefeature) / ⁠[_GetXStateFeaturesMask_](https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-getxstatefeaturesmask) / ⁠[_SetXStateFeaturesMask_](http://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-setxstatefeaturesmask), which older Windows SDKs do not declare for _AArch64_.
