IMAGE_FEATURES do not refer to individual packages, they are specially defined package groups (or behaviours in the case of e.g. package-management). If you have a look at classes/core-image.bbclass and classes/image.bbclass you can see how the package groups are set up (PACKAGE_GROUP_featurename). As you found, at the moment there is nothing checking that features in IMAGE_FEATURES are valid, thus as there is no PACKAGE_GROUP_helloworld and nothing checking for "helloworld" in IMAGE_FEATURES, it does nothing. However, if all you want to do is add a few specific packages it's just fine to add their names to the end of IMAGE_INSTALL - IMAGE_FEATURES might be overkill.
