@next is confusing across all packages
We should standardize how we address packaging this version-wise, and then go out to all packages using Koa@next and let them know of the standards.  This is super confusing to end-users.  It seems like Koa@next is unstable by not being the latest.  Is Koa@1.x even really used as much as Koa@2.x?  It's just super confusing to package maintainers to have to make a version that's not the latest but SHOULD be used (since it's newer/better - we should just add deprecation notices to people if they install a new version that is using koa@next?  maybe we standardize the deprecation notice?).
