I disagree with your interpretation: present in the routing table does not imply being used. I used to take it as a good sign, but now I believe it is a very low bar - someone thought to apply for the address space and succeeded in configuring a BGP session somewhere. Maybe they really use it and maybe they don't; it's just not a very useful metric. Note that "arguments supporting the proposal" says that the status quo is actively troublesome for users of IPv6 PI space: to get a /22, they have to disrupt their IPv6 installation to return their PI assignment and get a PA allocation. Having this in policy is currently doing harm to IPv6, and we can do better outreach than this.
