I recognised this and was the one who put David up to this. :-)

Other things, such as grokking EMBRs to allow boot from extended partitions,
or support for serial console other than COM1, can't be done in the 512-byte

But because of system incompatibilities, I would emphasize boot0ext remain
purely optional; and added to son-of-sysinstall with the relevant warnings.
