So my v2 version of the patch series added a new special case
helper tail function to do that:
https://lore.kernel.org/dri-devel/20251118-mcde-drm-regression-v2-3-4fedf10b18f6@linaro.org/

It was politely NACKed for complicating the helpers library (short story).

It's part of the trail of how we got to this current patch series.
