I, personally, use the term Bishop to ensure the Goldeneye 007 canon weapon modeled after the Walther WA-2000 and the non-bullpup sniper rifle in Goldeneye Source are distinct. (It was modeled during the "whatever we dream it should look like" era. That era ended when a monstrosity was called "Klobb" and everyone bricked.) In addition to the difference in appearance, the GES sniper rifle deals greater damage. This is part of a balance correction I am implementing to keep pistols from exploiting the ease of aiming on PC, and to keep the sniper rifle ahead of the automatics.
Whether or not Bishop Sniper Rifle ever appears in the game is up to KM since he's in charge of breaking and repairing the event notification strings. I wouldn't be adverse to having both the WA-2000 and Bishop both availiable with the difference being model and damage, similar to the Rocksalt Shotgun and Automatic Shotgun pairing, but that's not a critial concern at the moment.
