Cache partitioning make it useless to rely on the ressource previously downloaded by another website. This means the primary benefit of shared public CDNs is no longer relevant for any modern browsers.
Other arguments:
- Security concerns
- Privacy concerns
- Reliability problems
- Performance limitations
I like the example of HaveIBeenPwned, that shows how important caching and serving resources only can be efficient.
Another solution could be IPFS, but is not production ready.
