Seems to be unclear(at least to me), whether ever used or never
...while absolutely possible that you`re  right here.
` have discussed that with Rob Crowston & Mike Karels some time ago, 
The problem was the bcm2711-rpi-4-b.dtb , which at that time shouldn’t be changed because to stay compatible with the 8GB-model.,
so possibly since then there never was a newer dts compiled to dtb.
But I  G U E S S(still can’t resist;-) that we now have to patch&compile( at least bcm2711-rpi-4-b)  to stay in touch with 2020.10

Tomorrow I will look again exactly with which partition tables I booted the SSD, 
for today I am completely dizzy from all that rpi-dtb stuff , I can’t remember what I did :-)
