- An oversight of #48615 is that it changes the `Rails.logger` to be
  a broadcast logger after the app is booted. Anything referencing
  `Rails.logger` during the boot process will get a simple logger and
  ultimately resulting in logs not being broadcasted.

  For example `ActionController::Base.logger.info("abc")` would
  just output logs in the `development.log` file, not on STDOUT.

  The only solution I could think of is to create a BroadcastLogger
  earlier at boot, and add logger to that broadcast when needed (instead
  of modiyfing the `Rails.logger` variable).
