Some will say that this would create small genera unnecessarily so we might as well keep a large genus, even if imperfect. Otherwise, we might as well split Bubo stricto sensu into 3 genera to have a coherent taxonomic balance between each lineage.But Bubo as defined now is very unlikely to be wrong.
There's at most 8 species in Ketupa that might change genus when new studies come out.
If you lump everything in Bubo now, you need to change 15 species later...
