Hi, good question, I think it was just an effort to limit the scope of the
feature initially.  Over time we can possibly expand the scope after
seeing how things were working technically, and the experience of users.
I'm curious to know what configuration you're trying, and if you have any
experience using raid+integrity otherwise.
