How to add multiple worlds to player loop for Tiny/ DOTS Runtime?

I need multiple worlds in my Tiny project and have written an ICustomBootstrap. However, I don't see any documentation nor forum posts on how to add a new world to the player loop in Tiny/ DOTS runtime. The suggested way of using ScriptBehaviourUpdateOrder only works for the classic Unity runtime.

How do I achieve multiple worlds in the DOTS Runtime?

 

So I did some poking around in the DOTS Runtime code, and it looks like the DOTS Runtime does not support multiple worlds at all.

But I found a very quick workaround by changing the main Update method:
com.unity.dots.runtime@0.32.0-preview.54\Unity.Tiny.UnityInstance\UnityInstance.cs

Code (CSharp):

1.  
2.         public bool Update(double timestampInSeconds)
3.         {
4.             var shouldContinue = true;
5.  
6.             if (m_BootPhase == BootPhase.Running)
7.             {
8.                 switch (m_RunState)
9.                 {
10.                     case RunState.Resuming:
11.                         m_RunState = RunState.Running;
12.  
13.                         m_StartTimeInSeconds = timestampInSeconds - m_ElapsedTimeInSeconds;
14.                         m_PreviousElapsedTimeInSeconds = m_ElapsedTimeInSeconds;
15.                         goto case RunState.Running;
16.  
17.                     case RunState.Running:
18.                         ComputeTime(timestampInSeconds);
19.                         *m_TimeData = new TimeData(
20.                             elapsedTime: m_ElapsedTimeInSeconds,
21.                             deltaTime: (float)m_DeltaTimeInSeconds);
22.  
23.                         DotsRuntime.UpdatePreFrame();
24.  
25.                         // ORIGINAL CODE
26.                         // m_World.Update();
27.                         // shouldContinue = !m_World.QuitUpdate;
28.  
29.                         // ~CUSTOM~ CODE
30.                         foreach (var iWorld in World.All)
31.                         {
32.                           iWorld.Update();
33.                           shouldContinue &= !iWorld.QuitUpdate;
34.  
35.                           if(!shouldContinue) break;
36.                         }
37.  
38.                         DotsRuntime.UpdatePostFrame(shouldContinue);
39.                         break;
40.                 }
41.             }
