public static final Set<String> DEFAULT_TRUSTED_CUSTOM_FIELD_TYPE_KEYS
As custom fields don't store their values in one single standardized way we divided them into two groups: trusted and untrusted custom fields.
Trusted custom fields are fields for which we can track their usage with 100% accuracy.
For untrusted custom fields we collect usage information, but the data might be not complete.
