Registroid auto registration silently fails

[PaintNinja]

The DeferredRegister is never registered to the modBus, with no compiler errors or warnings.

Here's the item class and its compiled output:

@CompileStatic
final class CoinItems {
    @Registroid
    public static final DeferredRegister<Item> ITEMS = DeferredRegister.create(ForgeRegistries.ITEMS, NinjasCash.MOD_ID)

    static final Item ONE_PENCE = NinjasCash.newBasicItem()
}

public final class CoinItems implements GroovyObject {
    public static final DeferredRegister<Item> ITEMS;
    @Generated
    private static final RegistryObject<Item> $registryObjectForONE_PENCE;

    static {
        DeferredRegister var0 = DeferredRegister.create(ForgeRegistries.ITEMS, NinjasCash.MOD_ID);
        ITEMS = var0;
        RegistryObject var1 = ITEMS.register("one_pence", () -> {
            return NinjasCash.newBasicItem();
        });
        $registryObjectForONE_PENCE = var1;
    }

    @Generated
    private static Item getONE_PENCE() {
        return (Item)$registryObjectForONE_PENCE.get();
    }
}

And here's the main mod entrypoint class:

@CompileStatic
@GMod(NinjasCash.MOD_ID)
final class NinjasCash {
    @PackageScope static final String MOD_ID = 'ninjascash'
    
    NinjasCash() {}

    @PackageScope static Item newBasicItem() {
        return new Item(new Item.Properties())
    }
}

@GMod("ninjascash")
public final class NinjasCash implements GroovyObject {
    static final String MOD_ID = "ninjascash";
    private final GModEventBus modBus;
    private final IEventBus forgeBus;

    public NinjasCash() {
        GModEventBus var1 = GMLModLoadingContext.get().getModEventBus();
        this.modBus = var1;
        IEventBus var2 = MinecraftForge.EVENT_BUS;
        this.forgeBus = var2;
    }

    static Item newBasicItem() {
        return new Item(new Item.Properties());
    }

    @Generated
    public GModEventBus getModBus() {
        return this.modBus;
    }

    @Generated
    public IEventBus getForgeBus() {
        return this.forgeBus;
    }
}

The issue persists with CGL 0.3.6
