This may be by design, which wouldn't be a bad decision as it adds to the replayability, so take this as a question rather than a complaint:
I've scanned everything, including the deep scans, and analyzed every anomaly, but I still have 6 open "slots" in the breakthrough chain (and yes, I know that there are more, because I never got Extractor AI, which is the one I really, really wanted, no matter what the cost (seems kinda tough that you have to build a dome to extract a few metal from an out of the way deposit, then destroy the entire dome when it runs dry).
Is there any other way of getting breakthroughs, or are you simply just not meant to get them all in every playthrough no matter how long you stick it out?
