Personally I like these working arrangements and being able to dish up HTML safe in the knowledge that your frontend developer is getting what he needs complete with expected class tags and other markup to be styled. In the future it will probably be better for me as I won't be doing template files with fiddly PHP tags, instead I will be json encoding the requested data, e.g. an array of products. There is a whole lot of logic to getting that array of products, this you need the server for. Presentation of that data? That can be done with the new stuff. From this article I have a better idea of what might be the future.
