Thinking a bit about it.
In my implementation I'm keeping 2 lists of strings. One of required
configs and another one of optional configs,
So, I'm not keeping the policy on my lists, I'm keeping the config
property name. With this in mind, how this enum could help, so?
If you are thinking about a more efficient way to keep the lists,
please, let me know.
