Comment:
This release totally breaks stateless autoconfig for IPv6. With 1.9, `iwd` ignored IPv6, so the kernel was able to use its built-in SLAAC mechanism to configure IPv6 when router advertisements were received. With the new "support", `iwd` unconditionally disabled router advertisement receipts by setting the `net.ipv6.conf.<interface>.accept_ra=0` sysctl. Furthermore, unless `EnableIPv6=true` or `EnableNetworkConfiguration=false` in the `main.conf` for `iwd`, it will also set `net.ipv6.conf.<interface>.disable_ipv6=0`.

I have not been able to restore old in-kernel IPv6 behavior, so the only way I can get SLAAC with this version of `iwd` is to force `EnableNetworkConfiguration=false` and fall back to `dhcpcd` for address assignment.
