It would be nice if graid got full support for RAID5 alteast I'm not sure
how much the others are used for that are not fully supported (RAID4,
RAID5, RAID5E, RAID5EE, RAID5R, RAID6, RAIDMDF) according to the man
page. I started to hack in RAID5 full support and try to avoid writes
if members didn't change. This limits our VROC support.
My experience, as co-author and maintainer of `sysutil/graid5`, shows, that it
is very non-trivial task. It contains many subtle problems.
`graid5` still has some undiscovered problems, and I don't think it worth
fixing in 2021, when we have ZFS for many years.
