I found this commit very interesting and it seems to also apply to this project:

Hey there. How do you suggest that we implement this? Add a reference to the documentation?

[syphyr]

yes, this should probably be added to the doc for users that want to default to ipv6 addresses.

[worstperson]

My situation is a little different since I'm sharing the connection through NAT, but I assign my addresses from the 2001:DB8::/32 range rather than ULA(FC00::/7). This is a reserved bogon prefix for use in documentation, perfect for use as a local address, and gets treated as a real IPv6 address by clients and browsers.

I just tried out wgcf and my wgcf-profile.conf on fedora has GUA address from the cloudflares address range. So now it prefers IPv6 by default.

If anyone else can confirm my observation, I think we can close this issue.

[syphyr]

Yes, it now defaults to ipv6. This change is no longer required.
