I'm not referring to SLAAC. I'm referring to addresses that are
configured on interfaces without the user even requesting them.
link-local addresses, specifically. Bring up an interface and you
have IPv6. Accessible (and attackable) by everyone on the local
network (i.e., not firewalled by default). Why do you expect this to
work without specific configuration (either setting up a static
address, configuring SLAAC, by using DHCPv6, or whatever means)?

I'm puzzled by the fact it has always been this way in OpenBSD. It
goes against the OpenBSD philosophy. I'll try to rephrase the
question:
Why do you expect that you are accessible on IPv6
when you configure an interface with IPv4? You
don't expect to get IPv4 connectivity when you
configure IPv6, do you?
I hope this question is less puzzling, apologies if that's still not
the case.
