Heavily Defended Precursor Anomalies

So I made a strong fleet(s) and analyzed 4 of the heavily defended Precursor anomalies. The ones that show up in red on the map. I didn't get prize in any of them.   If we don't get something for exploring them, then what is the use of them being there?  Only getting a message that someone got there first is just really annoying and makes me angry at the game. In GalCiv3 these anomalies often provided empire-wide benefits.  Now...Nothing?  

Please add some nice benefits for exploring these things.  Like before. Empire-wide bonuses to mining. finance or influence.  On some just 10-15 of strategic resource.  Make it worth the effort!
