And what if there 5 closely related but independently
volant "first birds" giving rise to at least a limited
diversity of "birds"? 

The question as usually phrased works if the smallest
clade containing Archie and _Passr domesticus_
contains neither _Confuciusornis_, nor
_Iberomesornis_, nor _Sapeornis_ - and if Archie
hadn't been found as early as it was, one might
habitually add _Dalianraptor_, _Jixiangornis_ et al.
If this assumption is not correct, all bets are off.
