Whilst I understand the rational for requesting an alternate solution, it feels unfair.  If the PR was to add a new OS or Vendor I'd have more sympathy but here we're talking about extending the existing OS-Vendor support to cover another target (i.e. x86_64-amazon-linux -> aarch64-amazon-linux) and so it seems fair to do so using the same method and maintain consistency.
