Looks good! Mind retargeting the PR to series/0.6 branch? After PR is merged to series/0.6, I'll merge to main as well so we pick up changes in both 0.6 and 1.0.

ok, I tried to re-target it in the same PR, but it got closed after I re-created the branch based on 0.6.x and can't reopen it :D. Created a new PR instead: #1041
