I find it surprising that this problem has never come up in IPv4. In IPv6 it could potentially be worse as hosts already have an address so the DHCP traffic can get in the way of real traffic, unlike with IPv4.

Could you explain what you mean here? This doesn't make any sense to me. The transport model for DHCPv4 and DHCPv6 are virtually identical, so I'm having trouble understanding what the distinction is that you're making.

The difference is that with IPv4, a host is unable to send data before completing DHCP negotiation, as it doesn't have an address yet. This isn't necessarily the case with IPv6 as hosts will configure an address for themselves based on router advertisements. So DHCP traffic and "regular" traffic may get in eachother's way when a bunch of hosts become online at the same time.
