There are needs to set default log configurations before passing them to setup_logging for ./wpt run. Here are some examples:

• Add ./wpt run --verbose as an alias of --log-mach-level debug #7846: make --verbose to be an alias of --log-mach-level debug.
• Document how to use ./wpt run --verify locally #15013: when running ./wpt run --verify failed, there is no detailed output for stability results. Adding --log-mach - can fix it, so might consider changing the default value.

All the log-related options are passed to setup_logging function to set up the logger.

Meanwhile, the setup_logging removes all the log_* items from args after setting up the logger:

The args then is passed to wptserver. As a reults, in #15012: --log-*-level was not passed to wptserve module, as the wpt server has a log filter and it doesn't know anything of the log configuration from command line at the wpt server side:
