As you said though, those users can reach v4 websites.

Its easier to get good latency and bandwidth over v6 than natted v4
What is the latency or bandwidth bottleneck in nat v4?
NAT registers in the microseconds for packet processing time, that isn’t even comparable to Internet path jitter.
Your typical router won't fill up its port mapping table. In fact, the 4th layer isn't involved at all so "ports" don't even exist as a concept.
There are already cases of Internet connectivity issues due to overloaded CGNAT. I know for a while I could only visit IPv6 websites, IPv4 technically works but the amount of packet drops meant that my IPv4 internet speed was only about 15KB/s!
It's the whole reason why I discovered a DNS server that synthesizes AAAA records, for websites that actually support IPv6 through their CDN. [0]

Therefore, the question is: Can those users really reach IPv4 websites?
Mind you, I don't expect the CGNAT-overloading issue to relieve over time.
