There is a better alternative to storing lists - https://www.mediawiki.org/wiki/Help:Tabular_Data -- it allows you to store a CSV-like table of data on Commons, with localized columns, and access it from all other wikis from the <graph> and Lua scripts.

A good example of it -- "per state GDP" page  -- see graph in the upper right corner.

Page: List_of_U.S._states_by_GDP
Data: GDP_by_state.tab

Wikidata is not very well  suited for lists data, but tabular data was designed for a relatively large (up to 2mb) lists.
