Looking at the research tree, I noticed two strange inconsistencies when playing a tribal game.
The first being Sterile Tiles, which doesn't seem to have a particular reason to be post electronics research. I also find it strange that you can make sterile tiles before regular metal tiles, if you research it before Smithing. Because of this, I think Sterile Tiles should have Smithing as its prerequisite instead of Electronics.
The second was Packaged Survival Meals, which for some reason requires not only Electronics but also Nutrient Paste to research, despite not needing either to actually make them (because of fueled stoves). Thus, I think it should have neither as a prerequisite, and could then be researched immediately for any faction (of course, it already is for arrivals regardless).
