Will the incorporation of WinUI 3 into File Explorer affect the shell object model?

[amtopel]

Does anyone know if the upcoming new version of File Explorer, which will incorporate WinUI 3, will break the shell object model? Will there still be HWNDs for the shell views and whatnot? And what about the UIAutomation tree/events? Will those still be accessible like before? Thanks for any info.
