We have to know it, insofar as it resolves Toph's as-of-yet incomplete character arc from the original series and/or insofar as it forms the background for Lin's own character development. It should be pretty obvious that Lin's father plays a major role in the arcs of both characters, in one way or another; we don't necessarily need to know his actual identity in order for him to accomplish this, but it is necessarily for this to be done to finally stamp out the strangely-persistent idea that Toph simply adopted Lin (despite how OOC that would be for her), and that she must remain static and single all her life as many fans seem to insist on.
