@macfarla I’ve rebased the branch and pushed the to rerun the CI. The two failing checks were unrelated to this PR. Could you please approve the workflows? |

CI failures appear to be due to Maven Central returning 403s, unrelated to this change. Should resolve on re-run, the past two ci that failed before are now passing. |
