Just as a data point,

> I think we share the belief that the vast majority (all?) residential ISPs currently bleach ALL DSCPs to default for their residential customers, and so the 0x2A value will already be handled in the same manner, but these requirements and the (to be written) informative text will help ensure operators only deviate from that default state consciously.

“all?” / ALL would contradict with at least one measurement study. See:
https://www.sciencedirect.com/science/article/pii/S0166531619300203 <https://www.sciencedirect.com/science/article/pii/S0166531619300203>
(where at least the ARK nodes count as “residential”), and references therein.

Cheers,
Michael
