Also, specifically to this comment, I know this is a hotly-debated key prefix, it’s why I go through great lengths to say it is not a debate on the existence of the prefix nor is it a proposal to deprecate any key.
That is also why I purposefully made the proposal short (2 paragraphs and a table) so hopefully people actually read the proposal instead of rejecting based on a knee-jerk reaction or prejudices on the matter.
