I don't like it either. It's a compromise. But as RAID1/10 will soon be unusable due to URE probability during rebuild, I think it's a relatively good compromise for some users, some workloads.
An alternative is to move to 3-way raid1 mirrors rather than 2-way mirrors. Obviously you take another hit in disk space efficiency, but reads will be faster than you have extra redundancy.
