Look, there's already a good, well-thought-out solution. Use
neontological names for crown groups. Do it everywhere in biology.
Maximize cross-disciplinary understand. Limit unjustified inferences.
Need to refer to the total group? Use "pan-" (informally) or "Pan-"
(formally). Need to refer to the apomorphy-based group (assuming the
name refers to an apomorphy)? Use "Apo-". The stem group? Use "stem-"
Everywhere. Every part of the Tree of Life. Coleoptera.
Proteobacteria. Poales. Ciliophora. Rhodophyta. Anthozoa.
Euryarcheota. And, yes, Aves. Why make exceptions?
