Dokku is in use in production by a large number of companies. Those companies might setup Dokku on a single, large host - perhaps collocated somewhere - and not want to have downtime for their product(s). Others host a swarm of Dokku installations and also want to avoid downtime during deployments. I suspect that "most users" will actually bounce if a site is down for more than a few seconds, or at least become frustrated with the availability of the site they are accessing. Aside, I'd rather not field support requests from folks about how one of the main features Dokku promotes doesn't work when they configure it one way or another.
