Closing this PR as un-reviewable due to chained PRs with unclear dependencies.

For changes of this size, it's nigh impossible to review on a per-PR basis. Some PRs in the sequence are very unclear on why they "depend" on the previous PR. There are hundreds of commits but individual commits are not meaningful.

#32673 -> #32480 -> #32496 -> #32533 -> #32715

will (attempt) review of #32715 alone
