Well, Cloudflare does not launch anything. They acquire to build products. Look into all their recent product launches. They acquired a relatively small company and converted the founding team to a product team.
So, if you want them to build stuff, ask yourself, are there any "Docker Registry" startups out there. If jsdelivr/globalping is not keeping you busy enough... there is an idea
Honestly I would build it if I knew how to properly market it to quickly get users.
Globalping and jsDelivr took years to gain a meaningful user base
Yes, actually, there are. I've built https://clipper.dev. I'm somewhat focused on robotics/edge device use cases right now (handling large images in bandwidth constrained environments), but my storage costs are also 1/7th of DockerHub. It also enables device to device content sharing much easier than base Docker, will be much easier to do antivirus/vuln scans, some other side benefits.
If there's something you'd want out of a registry that you think the market would want, I'm all ears.
