I think special case is a bad expression for describing it. Style 1 
is an algorithm for calculating costs. Style 2 is picking costs by hand. 
By your definition, all algorithms would be special case of style 2. 

Problem with style 2 is that you need to change costs by hand and
that is tedious. On the other hand, if we supply some algorithms for
calculating, style of play can be changed easily by switching one
ruleset option.

I agree on using game.researchcost for style 2 also. Line 
      cost = advances[tech].preset_cost;

on tech.c function tech_cost should be changed to
      cost = advances[tech].preset_cost * game.researchcost /
      DEFAULT_RESEARCHCOST;

That way ruleset maker can use real costs and costs can still be modified.
