However you are right that you can get rid of the current /boot array; 
I don't see the need for a separate /boot, its contents could be 
included in the root filesystem.

and the initrd lives where?
chicken / egg

In the /boot directory, beside the kernel image. What's different with 
the initrd ? I don't see any chicken & egg problem. If GRUB can boot the 
kernel image and initrd from a separate /boot RAID array, it can do the 
same from a root RAID array.

since finally the new machines in the next step only support UEFI and 
the uefi-system partition can't live on a RAID it would end there 
over time anyways

Software is not natively supported by EFI boot but there are a few

Oops ! I meant "software RAID".

tricks to set up a redundant EFI boot: create independent EFI 
partitions on each disk, or create a RAID 1 array with metadata 1.0 
(at the end of the partition) so that the UEFI firmware can see each 
RAID partition as a normal EFI partition with a FAT filesystem.

sounds all not appealing

Yes, but I know no cleaner way to achieve UEFI boot redundancy, which is 
desirable.
