The barrier for our company is that there's simply not much benefit to upgrading our AWS networking stack from ipv4 to ipv6. It's definitely doable, but there's no real benefit (especially when your infrastructure is behind Cloudflare (or any CDN) which adds ipv6 support for end users without needing the underlying infra to be ipv6. Even if we were setting up a VPC from scratch, it would probably be ipv4 since it's what everyone knows how to easily do. There's a learning curve with deploying a ipv6 network and very little benefit when it's all behind a ipv6-enabled CDN.
