Sorry about the slow reply. As a stopgap, looks good.

We should probably refactor this entirely to use a more robust system - it will yield inaccurate results when Mojang swaps to year-based versioning in 2026 because it assumed Minecraft would never hit 2.0.

I do have Version (and BukkitVersions) in PlanarWrappers already if we want to consider that for the future.
