yes becoming nitrogen deficient is more common naturally but both issues are common as alot of people do run gfo and po4 removers either before starting or during or both.
whether you need to run one or not would depend on the amount imported , and the ways they are exported......you can certainly out compete the bacteria in a closed system as they can only do so much , but yes i agree with the statements
both nitrogen and phosphorous can become limiting but both can also be added to the mix
