In the US, I really want the FCC to mandate that an ISP provides IPv6 connectivity in order to meet the criteria to be considered broadband (and access the subsidies related to that). Don't even care if the functionality is off by default / you have to call and agree the routing may be sub-optimal, whatever. I currently use HE tunnels but on top of additional latency, the HE <-> Cogent peering dispute still makes it difficult to access services over IPv6.

There should be rule that ISP with CGNAT must offer IPv6 as an alternative. The US doesn't use CGNAT as much as other countries, but would help people stuck behind crappy CGNAT.
