I personally cannot agree on that. Syncing /boot 'manually' adds much
more complexibility, unless you add scripts that automate the process.

I also wonder what's wrong in having /boot on a RAID1 partition,
because rescue mode should offer all necessary tools to mount raid
partitions. Instead I would suggest to add a separate page with common
recovery scenarios.
