Ideally, we should be able to specify which page handles to apply configuration generated css applies to, and the ability to implement multiple stylesheets.
<config>
....
<default>
<meanbee_configurationpoweredcss>
<css_blocks>
<default_css>
<block_type>namespace_module/config_css_default</block_type>
<handles>default</handles>
</default_css>
<products_css>
<block_type>namespace_module/config_css_products</block_type>
<handles>catalog_product_list,catalog_product_view</handles>
</products_css>
</css_blocks>
