Observable 0.1.3 for Forge 1.16.5
When adding the JAR to our server, our users - who don't have the mod in their client - will see that the server is incompatible:

According to Forge: A mod can register an extensionpoint for DISPLAYTEST telling the client to ignore the mod on the server. Something likeModLoadingContext.get().registerExtensionPoint(ExtensionPoint.DISPLAYTEST, ()-> Pair.of(()->FMLNetworkConstants.IGNORESERVERONLY, (version, network) -> {return true;}));

The Observable mod uses Kotlin and its init method where the above causes a build to fail on forge:compileKotlin.

Please implement an IgnoreServerOnly in the mod.
