Other than 3 and 5 they require difficult configuration. Mapping devices in GRUB isn't trivial. Those features are difficult to autoconfigure. Consider "plain" mode: how will you find which disk is yours when you have 5 disks all looking as random data?

Just wondering if there's any feedback on these patches... It's been a
while since I posted them.
