The POLICY_STORE_POLICY_PATHS_TO_IGNORE does not support the definition of paths in a negated way, like !myFolder.
It would be useful

Desired behavior:

• If !myFolder/subfolder/** is defined in the variable then all the contents of it should not be ignored, even if the path myFolder/** is defined to be ignored (eg: POLICY_STORE_POLICY_PATHS_TO_IGNORE=[myFolder/**,!myFolder/subfolder/**]
• If the only path defined in the variable is a negated one (or more than one), eg !myFolder, then nothing is ignored: the default behavior still is "nothing is ignored, unless here explicitly defined"
