This discussion has gone round and round a couple of times in different forms so I will avoid repeating my previous points but from working on PouchDB, the focus on having 'PouchDB' be a database only is fairly liberating, by not trying to add fairly arbitrary "application platform" features into the core codebase we can focus on integrating with what does provide those application platform features much better.
Users do not need to wait for reverse proxying or url rewriting to be an agreed, implemented and maintained feature, they can use the many that already exist and we will ensure that we integrate with their use case as best as we possibly can.
