I will watch with interest if the system collapses by oversplitting species and changing names into something nobody understands.
Or perhaps the system will wobble between the states 'oversplit' and 'undersplit' and 'lets invent more names' 'lets stick to names everybody actualy uses'?
The underlying system is that bird names and genera are invented, not found. There is no evidence that relations between bird species tend to follow steps called 'genera' 'families' 'orders' etc. So anybody can invent own bird names and genera.
Bird names and taxonomy are in constant danger for becoming useless, because somebody invents useless names for purpose of getting an extra paper published, prominence etc. A person inventing a new name or a new taxonomic shift has potential gain but zero cost (one can gain an extra publication, but one can lose nothing, simply the name is forgotten). Therefore, as more players join in and desire for prominence increases, the system moves towards chaos.
