I'd expect that to depend very much on the installation at hand (in our case it would), but that can't be decided programmatically. I'd opt for a way of skipping the initial-install wizard for advanced users. Possibly hidden below an "advanced setup” option and with a warning about being left without any usable account. But there should be a way of skipping it.
