> This setup has a benefit; namely, it is now impossible to brick the system with a bad BIOS/EFI flash, and you'll never need to use a hardware SPI flasher to recover.

T2 could have been designed to store / recover the rom in an SPI flash too. It's just cheaper to store it on the SSD

Or, in case of failure, just enable loading the fricking EFI bios from an alternative source. It's amazing the kind of nonsense people write because it's an Apple thing - machines have been able to boot diskless for very obvious reasons and requirements ever since the 8 MiB memory chip, but in 2021 we should go without that?

The amount of justifications for horrid design and engineering choices always touches the extremes when it's about Apple products.
