A simple one-time forwarding-configuration file pointing to the /boot volume UUID, permits configuration files to be written somewhere on /boot, which can then be md raid1 or btrfs raid1 based. Boot is made more resilient whether single or multiple disk. This works today on BIOS, but not on UEFI.

Sure. I just prefer being charged with one heresy at a time, and that particular one is much bigger than /boot/efi.

Unfortunately it may be too late to change this for RHEL 7, which means an ESP always mounted at /boot/efi may become a glorified tradition in any case.
