WixToolset.Dtf.WindowsInstaller not found

I am working on converting WiX 3 installers to WiX 4, as part of the conversion we are seeing the below exception when performing an upgrade (minor release)

System.IO.FileNotFoundException
  HResult=0x80070002
  Message=Could not load file or assembly 'WixToolset.Dtf.WindowsInstaller, Version=4.0.0.0, Culture=neutral, PublicKeyToken=a7d136314861246c' or one of its dependencies. The system cannot find the file specified.

When I add WixToolset.Dtf.WindowsInstaller.dll as a payload, the issue is resolved. Is this an expected behavior ? since adding it as a payload is not covered in the documentation

Documentation: "The Bal WiX extension does not add WixToolset.Mba.Core.dll or mbanative.dll so both must be added along with all the other dependencies of the MBA"

This part of the documentation applies to you:

along with all the other dependencies of the MBA

Your managed BA must depend upon WixToolset.Dtf.WindowsInstaller.dll.

Thank you for the confirmation
