The Galactic Guide Book wouldn't be that useful even if anomalies regenerated. I've built it before (why not), and while it does make the survey modules free, they still take up space. About the same space as 2 sensors. Galactic GB needs to be much cheaper and buildable earlier in the game; that's all there is to it.
I have never built the galactic guide book but in it's description it clearly say's that 'all' ships can servey. So if ships without servey modules cannot servey then that description would be an outright lie?
