It's a concern, but fortunately if cattle population stays constant, their portion of the atmospheric resident methane will also remain constant, because methane degradation will keep pace with emissions.
Compare this to cars. Even if the number of cars remains constant, their contribution to the C02 pool grows every day.
So we should avoid increasing cattle population 100x, but we wouldn't want to do that anyway because we'd have nowhere to put them, and I certainly wouldn't support deforestation.
