Use `/` as the default status endpoint

It seems strange to have the default status endpoint set as
`/status/check`, as most people do not implement this as an endpoint in
their web applications. The `/status/check` endpoint is more of an
internal convention than a community standard, so we should default this
to something more likely to be able to report an application's health.
In most cases, the root path should simply work for this out of the box.

I actually disagree with this; I feel like that's advising people to go against resourceful routing. "Check" is a verb and unnecessary in the URL. Sure we use /status/check internally, but if it weren't already a pattern here I would have advised against it earlier. "GET /status" makes more sense as a RESTful/resourceful route
