That's the thing that confused me too.
A border router will sent this 'final RA', but it's still a router, so my interpretation was that this can't signal "I'm not a router".
And when I added the RIO, Linux would just do the right thing and create a

```
2001:16b8:4545:14f8::/62 via fe80::a4ed:29ff:feec:cbf3 dev eno1 proto ra metric 100 pref medium
```

so I was happy.
