In a non-local environment, it is recommended that your log level should not be set to debug because of various cost factors:

Cost of Processing: If you use a third party service to accumulate logs across your servers, there will be incremental costs for processing logs based on your service provider.
In an effort to make upgrading the constantly changing config files
easier, Shift defaulted them so you can review the commit diff for
changes. Moving forward, you should use ENV variables or create a
separate config file to allow the core config files to remain
automatically upgradeable.
