Lightweight rowing is pretty much dead, anyways.

It was originally introduced to give countries with shorter people a chance to compete (as rowing depends a lot on height), but in practice it mainly resulted in promising candidates who didn't quite make the cut for heavyweight being forced into eating disorders.

Lightweight rowing has been cut from the olympics already, so to a lot of organisations it has lost its relevance. There are still world championships, but I bet it is only a matter of time before it'll disappear there as well.
