Cloudflare definitely isn't with their Durable Object design. As an infra developer/Django user myself, I know it's a pretty big paradigm shift to think in the 1 DB per user realm.

However, I do think it'll unlock "globally available" apps as a first class citizen moving forward. If Uber were made today, I suspect it'd follow the 1 DB per user and be deployed really close to the edge with providers like Fly.io, Koyeb, or Cloudflare.
