::As for coverage of the support and criticism of a model being unwieldy, that can likely be addressed by  summary style and structural/compositional choices. E.g. rather than list every paper for or against a theory, and their respective internal details, an encyclopedic summary can be condensed into a few paragraphs structured as "Most studies support X such as (selected examples), while a few studies Support Y such as (selected examples)." References to relevant review articles can further increase the coverage and balance of evidence without going into potentially unnecessary detail.
