Banning the creation of characters from both factions in Fresh PvP/

As already known from the preliminary announcement of the new Fresh Classic servers, only 1 PvP realm will be available. Which immediately raises an urgent question. Players will find themselves in a situation of choosing (*virtually no choice) only one faction in the Alliance or Horde, and it will be impossible to play for an alternative faction, since even PVP realm are only 1. Perhaps there is some information about the imminent cancellation of this ancient ban on 2 factions in PVP realm? In this case, this limitation is very serious, especially in the new realm, where there is simply no physical opportunity to just look at and study both factions in PVP realm.
