Well, we do know exactly who it is, we just can't say it on tv.Yang all but said that Mai and Zuko get back together after three years apart, not to mention Izumi's name is heavily implied to be a reference to the fountain incident of Mai and Zuko's youth and Izumi's design is almost a copy and paste of Mai's.
Besides, the only reason why we don't know who Izumi's mother is is because we needed cheap relationship drama to sell comics since they probably felt the mystery of what happened to Ursa, and later Azula, would not be enough to keep engaged with the comics.
