Excuse my ignorance but could someone explain to me why this is not the default setup (or an optional setup) in the 30 min install guide?

I understand that using two containers [minimizes the downtime during rebuilds](https://meta.discourse.org/t/faster-rebuilds/40341/13) and since nobody likes downtime, it seems like everyone would want two containers…

In other words: what’s the catch?
