It's not likely to be useful, but we do have system APIs which provide nanosecond level resolution, so why not make it available. Users don't have to specify timeouts with a nanosecond level. They can just say `std::chrono::seconds/*or whatever*/(X)`, and it will be automatically to nanoseconds.

Using a lower precision would actually be somewhat unergonomic chrono conversions which lose precision are not implicit. So something like `steady_clock::now()+seconds(2)` would not be implicitly convertible to milliseconds if the clock resolution was more than milliseconds (which it usually is).
