Service we provide could be from web development to generating contents. (Note that this is not necessarily true if you want content generated by an app server or any other tools which are able read data through TCP socket.) Some developers may need specific types of source files where a file type and some metadata must also be known as part the information provided in configuration options, because they require special handling for certain kinds. For example if there is already something similar with JSON here, then no additional documentation would help them create such module / function etc.. So these will probably have their own site directly (or just write one on github) so I think it'd make sense to say 'for now' under more generic term
