In verbose mode there are hundreds of these "checking PREFERRED_PROVIDER_%s" messages, cluttering the output and obscuring the more important resulting "selecting %s to satisfy runtime %s due to %s" messages. Individual "checking" lines are more suited for debug mode, similar to "sorted providers for %s are: %s", hence convert logger.verbose() to logger.debug().
