That's like saying that it's possible to find a real orbit which has an
eccentricity of exactly 0 or exactly 1 (not just very close, or equal to
the limit of precision, but precisely). One can talk about such things
in a mathematical idealization, but in the real world there's no way to
have such situations.

But this is completely undemonstrated.
