The question is, why do APIs return 64-bit values? In general it's not because they need all 64 bits, it's because the 64-bit integer type is convenient for them. This might make Crockford's proposal completely impractical but it doesn't invalidate the argument that led to it.
I reject the nanosecond example because it's completely arbitrary. 64 bits of picoseconds would only cover 0.584 years so should we claim 64 bits isn't enough? Wouldn't 2000 years of microseconds in 56 bits be good enough?
I'll give you credit for bitboards though, that's one I hadn't considered.
