Definitely hope the stance changes. Surely someone pretends red river hogs, babirusa and warthogs aren’t suids so we can have them too. Might add, red river hog would be a great species for any Congo precinct, and their popularity within planet zoo reflects that
Species are continuously reclassified - which is a double edged sword . Changes are readily proposed, but slowly accepted as they can just as easily change again in the future.
One example is the reclassification of all tiger subspecies into two subspecies - Mainland or Sunda Island. I’ve yet to see a zoo so much as relabel their Sumatran tigers as Sunda Island tigers - a comparatively innocuous move compared to the irreversible decision to breed a Siberian tiger with a Malayan tiger.
