If someone else ships a 100% solution, or a solution that doesn't have the problems your potentially half-baked "80% solution" does, then you might be in trouble. There's a fine line here: it matters a lot whether we're talking about a "sloppy" 80% solution that later causes problems and is incredibly hard to fix, or if it's a clean minimal subset, which restricts you (by being the minimal thing everyone agrees on) but doesn't have any serious design flaws.
