I don't believe it.- Habitats are great from a cost/benefit perspective for Research -snip-
Even with the recent slight nerf to research complexes, one can easily manage ~100 researcher jobs on a single dedicated research planet, and a base research production of >350 per category. Stacking a whole lot of modifiers can get this up to around ~1k research. Precisely how many habitats do you want to make to match that level of research?
