I see. But we are at risk like that for almost any definition - unless
we use a particular specimen and not a collection of individuals, even
some species ended up being paraphyletic! Right, we could take more
risks with higher taxon as specifiers.

But... what risk? Ah! Risk of having to modify the definition... not a
so cumbersome problem.
