I agree about this, given our current understanding. However, if you were
able to plan things millions of years in advance, as I think such a project
would demand, then might it not be possible to hide a lot of the work?

That another possibility. What about extracting energy from areas where it
would be likely for it to be noticed?

I agree, though given the surprises of the last several years of "planet"
discoveries, I wouldn't be shocked if planets were found in the stranger
places -- even planets with heavier (carbon and above) elements.
Of course, maybe the gamma ray burst are really Jupiter brain societies jump
starting before they stealth.:)
