Of course, I've tried that already with an USB installer for Catalina 
(APFS support) and El Capitan (pre-APFS) - both installers panic on boot 
while probing local hardware because as soon as they find the disk and try 
to read the partition table something goes kaboom.

Internet Recovery leads to the same results, because basically it's just 
another delivery way for the installer, but as soon as it starts booting 
were're at square one.

Is there some way to zero the first blocks of the drive from EFI :) ? Like 
in the old good days when Sun still shined, I could enter OpenBoot by 
pressing the magic "Stop-A" button and enter the Forth interpreter to do 
stuff like that...
