True. But Sangster clearly *intended* for Mirandornithes to be limited to
grebes and flamingoes. The clade was erected solely to emphasise the
(perceived) unique relationship between the two.
To my way of thinking (and I could be wrong here), the only way to guarantee
that Mirandornithes can *only* include grebes and flamingoes is to have
multiple external specifiers drawn from every neognath 'order' outside of
Podicipediformes and Phoenicopteriformes.
One way to avoid Mirandornithes becoming a heterodefinitional synonym of
Neoaves would be to amend the definition to include one neoavian taxon as an
external specifier (_Passer_ would work). Mirandornithes might include
several bird 'orders' (including grebes and flamingoes), but it would never
swallow up the entire Neoaves.
