Not a counter-point, but: the other day I rebuilt my personal server, finishing by pointing the reserved IP at the new box. I then had a period of confusion because I was still seeing old content, because my browser (etc) was obviously querying the AAA record first, which I hadn't updated.
(a while ago I needed to contact support to get an IPv6 allocation at home, but that was a very quick interaction at the time)
