This may be a minor startup perf win (as env_logger does not need the expense of DoS resistant hashes) but my main reason for doing this is that the default hashing algorithm depends on random number generation, which may fail. This is important to avoid especially because env_logger is often used on program startup. This was a real issue on Windows. While that specific issue is now fixed, it would be nice to avoid this class of issues if possible.
