I think the scale would be the problem. Debian is 5TB. Five years ago when Docker changed a storage policy they said it would save 5PB. I can't find the current size of Docker Hub. That's a huge cost to expect from a free mirror service, especially when a large fraction is of very limited interest, and unlike a Linux distribution Docker Hub isn't organized. (It's easy to only mirror the AMD64 packages for Debian, for example.) The Docker client also isn't able to work with a partial mirror.
