Since this mod rewrites the way research labs work (they no longer provide the base 1/1/1 of each type), there are only two buildings left that provide all research types (Research Institute and Computational Array) and to the best of my knowledge one building that provides two of the three (Military academy).

First concern: Some mods, special events, or planet modifiers generate tiles with bonuses of all research types. Although rare, the player must choose whether to develop the building and lose the other types, work the tile undeveloped, or move their capital there to build the Research Institute (as Computational Arrays are tile-restricted.)

Second concern: It seems that the tier 3 version of all Megastructure Node buildings are balanced to provide three raw units of whatever resource they provide, and three units worth of adjacency bonus to each adjacent tile. The Computational Array does offer three raw yields (1/1/1 research) as well as and adjacency bonus worth three in total; however, no building except the exceptions will be able to make use of all three bonuses — the bonus can only be collected if the building produces the same yield originally. So the adjacency bonus is effectively 1, not 3. The Computational Array is weaker in comparison to the Energy Conduit, Energy-Matter Converter and Food Replicator.
