Never mind, this was user error. :) I have a kickstart that discard unused space in %post to make VM images smaller, and it tries too hard (and the SSDs listened!) - it got the unpartitioned space between the partition table and the first partition, and GRUB2 uses more of that when /boot is on RAID1.
