Remove the feature to preload relations from the root line¶

Issue¶

The method RootlineUtility:enrichWithRelationFields() preloads relations for each page.

This causes a bunch of additional DB queries per page request.

Discussion¶

• The feature is rarely used while the costs are rather high.
• There are several comments on unclean implementation.
• No unit tests are breaking if the feature is removed.
• The official introduction package keeps working, if the feature is removed.

Alternatives¶

• Load the information on demand.
• Think of an intelligent design of page record objects, that enable loading on demand or by configuration.
