It would be great to move storage drivers to their dedicated go modules in dedicated repositories. Specifically, any drivers that have external dependencies (i.e. anything other than the Go standard library).

This would provide several benefits:

• Each driver provider could be maintained by their domain experts
• each driver could be versioned independently of the main distribution project and thus be used by other similar projects

Ideally we aim to be in a position where only inmemory and filesystem drivers are in the core project repo.
