"cweagans/composer-patches": "^1.6",

As discussed in localgovdrupal/localgov_core#23 will patch if the parent composer.json has required cweagens/composer-patches and enable it. It won't if it doesn't.

These patches are required for the functioning of the module? If so a note can be added to the readme or similar to the effect that you need to require and enable cweagens/composer-patches if isn't already in your parent composer.json for it to work correctly.
