API surface: This method in Rx.NET has about 48 overloads, do we need all of them (0-11 arg Action, 0-11 arg Funcion, x2 with scheduler overloads)?

Schedulers: In Rx.NET the scheduler-less overloads use the SchedulerDefaults.AsyncConversions which in turn is a DefaultScheduler. So do we use the Schedulers.threadPoolForComputation() directly or introduce a Schedulers.threadPoolForAsyncConversions()?
