I think I've seen this on the list before. Naturally, several problems:
1) They lacked reptilian synapomorphies; you could say "basal
2) ... some were fairly derived themselves.
3) While Ax did suggest including them as mammals, his extension of
popular taxa to include all stem lineages has not proven popular at
all: nobody wants to call _Triceratops_ an avian, _Stagonolepis_ a
crocodylian, etc. The reverse solution, restraining popular taxa to
crown clades, has proven much more effective (although in some cases
still contentious, e.g., _Aves_).
