To give another example, in spain most mobile carriers will place everyone behind a cgnat with no ipv6.

In fiber some do the same, although thankfuly most place v4 behind a cgnat while offering ipv6.

The whole 1 ip 1 user even if dynamic quite false and is a mess.

That has been my experience on any mobile network, also in 2007 or so when v4 addresses were still available (because my 15-year-old self wanted to seed torrents with my unlimited data bundle ...on GPRS). It's a fair point that one has to consider this part of the market, though I was primarily thinking of wired connections.
