Fired up a DO SGP droplet to test. Still no /64, but they give you a range of 16 addresses, so that's an improvement.
If there's one thing besides lack of adoption that will kill IPv6, it's providers not knowing how to set it up right. I know most LE hosts around here don't do /64s because SolusVM doesn't allow it (yet another manifestation of this problem). DO had a chance to do it right, and it seems they weren't up for it.We are currently only providing 16 IPv6 addresses per server. We hope you can understand.
