Each entry is a dictionary with a 'name' and a 'section' key. We end up with:

The 'name' key might get dropped as redundant, but it's useful for debugging.
TODO: Drop the 'name' key as redundant. For now it's useful for debugging.
This list is only used to filter config-defined options from those defined elsewhere.
Because the option names are the keys, only the last occurrence is retained.
Use the Schema class for a more complete list of options, soon with full parsing.
This list is used to filter what is actually a config-defined option versus
defines from elsewhere.
This means the actual used value might not be reflected by this function.
The Schema class does more complete parsing for a more accurate list of options.
While the Schema class parses the configurations on its own, this script will
get the preprocessor output and get the intersection of the enabled options from
