EDIT

we have a couple of init-strategies which still include the representations:

DescriptionElementController.java
 66: "states.state.representations", 
DescriptionElementListPortalController.java (2 matches)
 45: "name.rank.representations", 
 46: "name.status.type.representations", 
FeatureTreeListPortalController.java (2 matches)
 32: "root.feature.representations", 
 33: "root.childNodes.feature.representations" 
FeatureTreePortalController.java
 56: featuretreeNodeInitStrategy.add("feature.representations"); 
NameController.java
 51: "typeStatus.representations",  
NamePortalController.java
 67: "typeStatus.representations", 
TaxonPortalController.java (7 matches)
 116: "name.rank.representations", 
 117: "name.status.type.representations", 
 133: "name.rank.representations", 
 134: "name.status.type.representations", 
 143: "synonyms.name.status.type.representations", 
 193: "name.rank.representations", 
 194: "name.status.type.representations", 
TaxonPortalListController.java (2 matches)
 32: "name.rank.representations", 
 33: "name.status.type.representations", 

All these are no longer needed and should be removed to speed up the controllers.
