I get that, and like anything it's a matter of trade-offs.

To me, in most cases, 4 or even 10 minutes is just not a big deal. It's fire-and-forget, and there should be a bunch of things in place to prevent bad deploys and ultimately let the team know if something gets messed up.

When there's an outage, multiple people get involved and it can easily hit 10+ hours of time spent. If adding a few minutes to the deploy time prevents an outage or two, that's worth it IMHO.
