In the new API, the model aware data holders have 2 getValue methods:

• <T extends Object> T getValue(String dataPath);
• <T extends Object> T getValue(String dataPath, boolean useDefaultFromModel, T fallback);

A new API's user would rather have signatures which look like:

• <T extends Object> T getValue(String dataPath);
• <T extends Object> T getValueOrDefault(String dataPath, T defaultValue);
• <T extends Object> T getValueOrDefaultFromModel(String dataPath, T fallback);

If we decide to change the methods' signatures, the config has to be impacted too.
