I think this shows that current taxonomic classifications are only an approximation to biological reality.
All classification schemes and all models are approximations to reality.
In this case, the current taxonomic schemes have been conclusively demonstrated to be excellent models of biological reality.
It looks as if you are promulgating the old YEC tactic of "we don't know everything therefore we know nothing". Yes, our classification is not perfect. It's still pretty near perfect and extremely useful.
