Graeme,
Why does it have to assume "perfect" anything? It does not have to. Take Fogra39. It's very close to an "ideal" print space, and has "real" color mixing with some sort of dot gain curve. Heck, GRACoL20xx is based on Fogra39?

It's perfectly feasible to create such a space - you would just assume perfect colorants and pure subtractive color mixing with some sort of dot gain curve.
If you sent it directly to press, you wouldn't expect terribly good color reproduction - it would just be a familiar space with a less restricted gamut, and the ability to specify the black ink reproduction (i.e. black only text etc.), and it would need color management before sending to a real press if you wanted something that looked good.
There are many other ways of achieving a similar technical result - i.e.
an RGB space with an added "text" or "black generation" channel, etc. etc., but the main obstacle is not technical, it's standardization and application & workflow support.
