I see. It would have to be a hook into the resource loader.
You don't need a hook in the server-side PHP part of the resource loader, as determining which modules to load on that side is already supported. The Gadgets extension's PHP code could inspect variables like $wgTitle->getNamespace() and determine whether to load a certain gadget or not.
This would of-course result in mangled cache for every page context that had a different set of page conditionals. Its better to do as you say bellow and have thin loader code check javascript conditionals and then fire off the loading of the gadget as needed.
I see your argument how separating gadget loading into a separate request might be better so as to avoid cache mangling, but I hadn't really considered that and was looking for ways to tack gadget loading onto the request loading statically requested modules (through $wgOut), which is possible by a custom loader.
Is this not what the mediaWiki.load.using() is for?
Yes, that's what you'd use in a thin loader module that then loads other gadgets as needed, but it'd result in loading the requested modules in a separate request (which seems to be what you want).
Are wiki page names addressable as loadable modules? Ie can you request mediaWiki.load.using(['MediaWiki:MyGadgetDepenency.js', 'MediaWiki:MyGadget.js', 'MediaWiki:MyGadget.css' ] , function(){ ... MyGadget.doStuff() .. }
No, that's not supported.
This was supported in the old resource loader via special WT: resource name pretext, but perhapse could be implemented more cleverly in the new resource loader. But would be nice to preserve the basic principal of being able to grab multiple wikipages in a single request, as to support more module gadget code.
I don't believe we should necessarily support retrieval of arbitrary wiki pages this way, but that's not needed for Gadgets: there's a gadgets definition list listing all available gadgets, so Gadgets can simply register each gadget as a module (presumably named something like gadget-gadgetname).
