So this feels like a contentious decision. It'd be awesome to have the options for the methods stored along-side the methods themselves. The downside with this is that the thing accessing the configuration data is always the plugin, so it's the plugin that must have requested the configuration option. This is also important in case the description of the configuration option needs modifying for clarity or providing context for how it will be used. If the interface changes, all plugins calling the plugin methods will need updating, so the config options can be updated if necessary.
