What happens if I pass a 64 bit integer, and the Rudder pipeline being in JavaScript silently down-casts it to a 53 bit integer? Segment's pipeline involves JS at some point. We had an issue where our 64 bit integers were down-casted silently. We found out the hard way. We use strings now (perhaps should have used strings right away, I am not necessarily the sharpest tool in the shed).
