> A good version control system would support petabyte scale history and terabyte scale clones via sparse virtual filesystem.

I like this idea in principle but I always wonder what that would look in practice, outside a FAANG company: How do you ensure the virtual file system works equally well on all platforms, without root access, possibly even inside containers? How do you ensure it's fast? What do you do in case of network errors?

Someone just needs to do. Numerous companies have built their own cross-platform VFS layers. It’s hard but not intractable.

Re network errors. How many things break when GitHub is down? Quite a lot! This isn’t particularly special. Prefetch and clone are the same operation.
