Briefly, with the patch, my RPi4B will now attach the USB controller and all dependant devices including genet0, and an attached SSD. The only thing that failed to work, was actually booting from the SSD with no SD card present, this caused a crash in U-boot. Details follow including links to the dmesgs.
