Usage of Bootstrapper.config in WiX 5

[yuvnith]

In WiX v3 we have BootstrapperCore.config file to inform the MBA host which .NET Framework runtime it supported and which DLL contained the MBA.

In WiX v4, the config file is named WixToolset.Mba.Host.config as the config file is still used

However, in WiX v5, it appears that the bootstrapper configuration file is no longer required. This is because Burn now launches Bootstrapper Applications as separate processes instead of loading them as DLLs within the Burn process.

Could someone confirm if this Bootstrapper configuration file is indeed no longer needed in WiX 5?
