Summary: The Rust store code has been enabled everywhere for a few weeks now, let's enable it by default in the code. Future changes will remove the config as well as all the code associated with the non Rust store code. The various tests changes are due to small difference between the Rust code and the Python one, the biggest one being it's handling of corrupted packfiles. The old code silently ignored them, while the new one errors out for local packfiles. The test-lfs-bundle.t difference is just due to an ordering difference between Python and Rust.
