@pwolfert Just wanted to bump this PR for possible inclusion in v12. Having this change would allow us to remove one of our patches.

@seesleestak, I know the patches aren't a pretty thing, but we're not yet ready to merge this until we get a final word about the pattern from our stakeholders. We'll continue to discuss this.

Understood, thanks for the update
