No, that's the whole point.
Imagine I've shared output of "ifconfig" on my machine, or "netstat" output, or logs for some network service which listed local addresses.
For IPv4, this will is totally fine and leaks minimal information. For IPv6, it'll be a global, routable address.
That's a pretty weird threat model. Like, yeah commands you run on your machine can expose information about that machine.
Especially as if someone is able to capture ifconfig data, they can probably send a curl request to a malicious web server and expose the NAT IP as well.
Or if you happened to curl ipinfo
Or if you had a script that did that and put the public v4 address in your taskbar.
