Maybe 3.0.
Edit:
Although... what does that mean? I think the Neo-Standard is just a naming convention for any types the mod might add. I don't think the Neo-Standard says "all mods should include all these types". So, I think the only way to not be "Neo-Standard compliant", would be to include a ship that is clearly like something in the Neo-Standard, but then ask for a picture called something else (e.g. "FunShipPic"). So in that case, Proportions has been "Neo-Standard compliant" for most or all of its existence. There are a couple of types Proportions has that don't match anything in the Neo-Standard: Starliner and StarlinerLarge, for instance, and InfantryElite.
