During a task investigation on August 11 T205268#6375947 we decided to split off a task to be picked up identifying which of the current `GenericServices` are actually generic and deserve to be in such as class, and which should be moved to `SingleEntitySourceServices` and `MultipleEntitySourceServices` etc.
Current public methods of GenericServices to be considered:
[x] getEntityNamespaceLookup - T260426
[x] getFullEntitySerializer
[x] getCompactEntitySerializer
[x] getStorageEntitySerializer
[x] getBaseDataModelSerializerFactory
[x] getCompactBaseDataModelSerializerFactory
[x] getLanguageFallbackChainFactory - T260431
[x] getStringNormalizer
Acceptance criteria:
[] List of services provided by GenericServices are categorized
[] Subtasks of T205268 have been created for the services that are not generic and need to be moved / changed.
