It's nice in that whole "I still have to use the internet for something even if the IT group toasted my internet by letting rogue RAs on a network without real IPv6 on it.

I wonder if our local hospital ever found the source of rogue RA on their patient WIFI network from a year or two ago. It wasn't handing out addresses, just a route. Totally hosed linux anytime you connected to it. I had to set up an ipv6tables rule to block all in order to use dual stacked sites there.

If I didn't know what I was doing, and running windows, that hotfix is certainly better than disabling ipv6 for good
