Summary: Several reasons: * We are fulfilling a promise that RCTScheduler is just a very thin interop proxy between C++ and Objective-C; * We have to pass all parameters down to Scheduler anyway, so instead of creating all of them separately and then passing one-by-one, we consolidate them into Context created where we have all those values. In the future, we probably will move it to some dedicated place. Reviewed By: mdvacca Differential Revision: D9884892 fbshipit-source-id: f1d5744e4044bc4bdfe53ec9a97ee61dcf0c60c2
