Temporary, maybe. Devices will be directly exposed to internet more often (either by misconfiguration or voluntarily) and they will have a more complex network stack in many cases. On the other hand, it will be much harder to scan the IPv6 address-space for vulnerable devices and there will be less complex network stack once we have abandoned IPv4 (no more NAT).
I think the benefits outweigh the cons by far with IPv6 since quickly scanning for vulnerable devices is a very strong reason why we see all the crap now. To have simpler protocols and simpler setups is also a good reason to strive for it in the long run as that benefits security as well. Temporary it will cause some issues (dual stacks and misconfigured setups due to lack of knowledge by the user/technicians) but that will quickly change when IPv6 become more common.
