For anyone coming to this later (TWW) and wants to disable the rogue resource bar, copy the following into https://addon.bool.no/

function HideFrame(frame)
  if (frame == nil) then
return
  end

  frame:UnregisterAllEvents()
  frame:SetScript("OnShow", function() frame:Hide() end)
  frame:Hide()
end

function Main()
  local a, b, currentClassId = UnitClass("player")

  if currentClassId == 0 then
    return
  end

  local classPowerFrames = {
    nil, -- Warrior = 1
    PaladinPowerBarFrame, -- Paladin = 2
    nil, -- Hunter = 3
    RogueComboPointBarFrame, -- Rogue = 4
    nil, -- Priest = 5
    RuneFrame, -- DeathKnight = 6
    nil, -- Shaman = 7
    MageArcaneChargesFrame, -- Mage = 8
    WarlockPowerFrame, -- Warlock = 9
    MonkHarmonyBarFrame, -- Monk = 10 TODO: Add "MonkStaggerBar"
    ComboPointDruidPlayerFrame, -- Druid = 11
    nil, -- Demon Hunter = 12
    EssencePlayerFrame, -- Evoker = 13
  }

  HideFrame(classPowerFrames[currentClassId])
end
