It may be handy for folks to get a purely net/http server implementation, rather than using a router.

This will be made easier by golang/go#60227 but could allow us to boilerplate a lot of the awkwardness that can be had with the standard library when we are doing things like URL path parameters.

(This is a suggestion while I remember, not intent to add it to the codebase unless we get interest!)

Should also include build tags
