Wikibase Lua methods for working with item properties like `mw.wikibase.getAllStatements()` and `mw.wikibase.getBestStatements()` should not load an entire item into the Lua memory. The difference between these functions and the methods of the `mw.wikibase.entity` object is that here we do not initially get all element statements. Therefore, instead of working in the same way as the methods of the `mw.wikibase.entity` object, they should only load into memory those data that were requested. A real example: if you want to display a list of country names with flags, then approximately 25 elements are enough to occupy all 50 MB of memory in Lua. Possibly related tasks: T179638, T76156.
