Has anyone considered the possibility that the number of units that can be supported by a strategic resource will be affected by tech? Seems logical. Research iron working, and that iron resource that your blacksmiths knew about but couldn't use too well goes from supporting one unit to five units. Figure out metal casting, and suddenly, it can support 20 units. Etc....
Would be in line with the vague explanations we've gotten in previews.
