It breaks Spark running on machines with less than 3 cores/threads, which may be rare, and it is maybe an edge case.
Personally, I like to fix known bugs and the fact there are other blocking methods in event loops actually makes it worse not to fix ones that you know about. Probably not a blocker to release though but that's your call.
