I don't love having vendored versions for everything except arm64-windows.
I think my preference would be vendored versions for all, with optional sourcing from (system) package manager. I also don't love how much bloat and churn that entails. Maybe arm64-windows is a special-enough case to push for vcpkg.

This isn't a blocker, just provoking discussion so we can form a stance here intentionally.
