It gets worse - because ISPs are choosing NATs over IPv6,

Yes, because they’re mostly pieces of shit, technically inept and unable to properly deploy IPv6 at a large scale.

Either way IPv6 doesn’t fix everything as you’ll still need a real IPv4 to access a large part of the internet or some translation (MAP-T/MAP-E). Even if your ISP provided dual stack with a real public IPv6 + CGNAT / MAP-T IPv4 it would still be annoying as you wouldn’t be able to do port forwarding on the IPv4 and won’t be able to access your self-hosted services from a LOT of networks that are IPv4 only.

There are two versions of MAP – translated (MAP-T) and encapsulated (MAP-E). In MAP-E IPv4 traffic is encapsulated into IPv6 using a v6 header before it is sent over the v6 network. At the network operator’s boundary router, the IPv6 header is then stripped, and the IPv4 traffic is forwarded to the v4 Internet. In MAP-T, the IPv4 packet header is mapped to the IPv6 header and back. The difference between the two options is evident in their names. MAP-E uses IPv6 to encapsulate and de-encapsulate IPv4 traffic, whereas MAP-T uses NAT64 to translate IPv4 to IPv6 and back.

Tried that and doesn’t seem to work. :(

Relevant documentation for others about -S / spindown_time:

Values from 1 to 240 specify multiples of 5 seconds, yielding timeouts from 5 seconds to 20 minutes. Values from 241 to 251 specify from 1 to 11 units of 30 minutes, yielding timeouts from 30 minutes to 5.5 hours. A value of 252 signifies a timeout of 21 minutes.
