HSRP vs VRRP for IPv6 on IOS-XE - rekindling an old flame

A while back I brought up a discussion about IPv6 and I mentioned having some HSRP issues. Not end of the world, just adjusting to IPv6. Several folks went offline to tell me that I should dump "legacy" HSRP and go to VRRP. While I never did find anyone who could explain how HSRP is a sunset feature in IOS, I did agree with a few folks to look into VRRP for IPv6. Well I'm just now getting around to it and there is literally nothing out there. I found a few older articles implying that it's not there yet and of course I found the usual docs about RAs and SLAC and whatnot. But nothing recent. So, for those who criticized me previously about using HSRP (or anyone else) instead of VRRP, do you have VRRP up and running on Cisco IOS-XE and if so how? Can anyone provide a link or a document explaining how this is accomplished? Sample configs? Usually if you can't find it on Google or CCO it's not promising. I'm also reaching out to our AS team for guidance on the subject.

PS: I'm not taunting here. It's just that several folks made the effort to go offline with me and tell me how wrong I was with HSRP and that I need to progress to VRRP and I can't find a single doc on the subject now that I look. Were these folks mistaken or am I missing something? Any help would be appreciated.
