So the bootloader doesn't need to understand md, and the rest can be taken care of in the initramfs/initrd (it's OK if said quickly and I slam the lid back down before the worms crawl out !)

Dunno enough about metadata version, but, yes, I experimented this
setup with md1 and it worked. If boot fails from the first disk, you can
ask the BIOS to boot from the other one and it works. It worked for
Grub-0.9 as well.
