Sounds like a forced sustainability measure to me. Nothing wrong if we're made into herbivores, except maybe the non-human herbivore populations running rampant and competing.
The competition is worse with the actual situation : cows are herbivore, pig are omnivores but fed plant-only. Chicken and fishes aren’t relevant for Alpha-gal syndrome but they’re also mostly fed by plants (and other fishes) anyway.
It may be counter intuitive at first but a vegetal diet needs less plants in total than an omnivore one.
