Of course there are some theoretical reasons for growing fast. But theory only gets you so far, on this issue. Rather, this question depends on whether growing EA is promising currently (I lean against) compared to other projects one could grow. Even if EA looks like the right thing to build, you need to talk to people who have seen EA grow and contract at various rates over the last 15 years, to understand which modes of growth have been healthier, and have contributed to gained capacity, rather than just an increase in raw numbers. In my experience, one of the least healthy phases of EA was when there was the heaviest emphasis on growth, perhaps around 1.5-4 years ago, whereas it seemed to do better pretty-much all of the other times.
