I could be missing it, but I'm not seeing how to do this. A hook called sometime before ApiMain::execute() would allow me to add to the list of formatter classes to implement alternative output formats. (I think this would be a cleaner way to implement server-side events than I currently have in https://github.com/worden-lee/cometdemo.)
Version: 1.23.0
Severity: normal
Rather than a hook, it might be better to do this with a $wgAPIFormatModules global, along the lines of all the other $wgAPI*Modules globals we already have.
While I can see how a hook might be useful, if used for adding modules generally it would probably be a performance hit versus the globals.
