config:get show default config.xml value

[rafaelstz]

Current Implementation

The current config:get doesn't show the default value from the config.xml if it's not in the database.

Suggested Enhancement

Check the default value in case there's no value found via DB.

This alias function does this:

function m2-config-get () {
  bin/mageru2 dev:con "\$di->create(\Magento\Framework\App\Config\ScopeConfigInterface::class)->getValue('$1');exit" | grep '=>'
}

Expected Benefits

[convenient]

Possibly a subset of #712

It would be neat if we could have config:store:get read default.xml, config.php, and env.php appropriately.
