The approach you have suggested is good one thing I would add is simply a note.
If the config item is only being used in one place the do not add it to the helper simply add it to the model that needs it.
In your approach you need two helpers for one config value which could be seen as a bit of overkill. Even if there is little or no performance implications with this approach it does appear to be complex for simply loading config values.
Follow bellow steps
Step : 1 (module.xml)
app/code/Ccc/HelloWorld/etc/module.xml
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
<module name="Ccc_HelloWorld" setup_version="1.0.1">
</module>
</config>
Step : 2 (routes.xml)
app/code/Ccc/HelloWorld/etc/frontend/routes.xml
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../lib/internal/Magento/Framework/App/etc/routes.xsd">
<router id="standard">
<route id="helloworld" frontName="helloworld">
<module name="Ccc_HelloWorld" />
</route>
</router>
</config>
Step : 3 (registration.php)
app/code/Ccc/HelloWorld/registration.php
<?php
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Ccc_HelloWorld',
__DIR__
);
Step : 4 (Index.php)
app/code/Ccc/HelloWorld/Controller/Index/Index.php
<?php
namespace Ccc\HelloWorld\Controller\Index;
use Magento\Framework\View\Result\PageFactory;
class Index extends \Magento\Framework\App\Action\Action
{
protected $resultPageFactory;
/** * @param \Magento\Framework\App\Action\Context $context */
public function __construct(\Magento\Framework\App\Action\Context $context,PageFactory $resultPageFactory)
{
$this->resultPageFactory = $resultPageFactory;
parent::__construct($context);
}
public function execute()
{
$resultPage = $this->resultPageFactory->create();
$resultPage->getConfig()->getTitle()->prepend(__('Hello World'));
return $resultPage;
}
}
Step : 5 (HelloWorld.php)
app/code/Ccc/HelloWorld/Block/HelloWorld.php
<?php
namespace Ccc\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{
public function _prepareLayout()
{
return parent::_prepareLayout();
}
}
Step : 6 (helloworld_index_index.xml)
app/code/Ccc/HelloWorld/view/frontend/layout/helloworld_index_index.xml
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd">
<body>
<referenceContainer name="content">
<block class="Ccc\HelloWorld\Block\HelloWorld" name="helloworld" template="helloworld.phtml">
</block>
</referenceContainer>
</body>
</page>
Step : 7 (helloworld.phtml)
app/code/Ccc/HelloWorld/view/frontend/templates/helloworld.phtml
<?php
echo 'Successful! This is a simple module in Magento 2.0';
?>
Step : 8 (rerun magento setup - this will re-generate app/etc/config.php & enable the module)
php-cli bin/magento setup:upgrade
I also flush the cache of the admin panel.

There's nothing wrong with including
config.phpin VCS if your needs are based on configuration being the same across various environments, especially the on/off states of your modules. The side effect of doing this is the limitation you impose on yourself in terms of having the same themes, language packs, etc on each one as well.For Magento 2.2 we're going to be making some improvements to add more flexibility to configuration management to support various deployment workflows. You'll have a file that is meant to contain all shared configuration
app/etc/config.php(meant for config that's likely to be the same across all environments and kept in VCS). You'll have another file that's meant to contain system-specific configurationapp/etc/env.php(meant to contain config that is likely to be different across dev, staging, and production systems).In the meantime, we've curated some deployment approaches from the community that you can find on this page in case it helps.
