Looking at the code, the only problem I can see is updating the Version class... This could be relatively simple, but may require to find out every possible output of Bukkit.getServer().getBukkitVersion() down to 1.8 to create proper changes to use as it seems to be a get package name -> check with enum of version patterns thing used here.

Perhaps getting the Bukkit version, doing some string transformations (i.e. split at - and use first part and replace dots with _) could already go a long way here... But again would we need to know all versions that the plugin should support and their respecive Bukkit version output... :/

Seems they've pulled the trigger on this.
