Roughly 20-40% of the web supports IPv6, and the number grows every year. Implementing it fully is a technical process, but it's not an impossible barrier. The real reason for the slowness is that there's little to no profit incentive to ensuring its full compatibility, in part because IPv4 is guaranteed to be (mostly) backwards compatible for decades. It's a slow process, but it's happening. There's no need to invent yet another standard for something that's already working and will likely be good enough to last generations once it's finished being implemented.
