Boot repair is obviously tricky because you have to have something
bootable to initiate the repair. Practically speaking, I think the
best option is to better support dual-drive installations. It should
be possible to maintain two EFI partitions in a, b style when the
user selects to have a mirrored-disk configuration. In fact I've been
doing this on my Fedora Linux systems and I've even written some
scripts to support it here:

Disclaimer though -- I use systemd boot and zfs, not the default grub
and btrfs that most Fedora Linux systems are configured with.
This is possible using standard efi boot with the cooperation of the
bios. Just use two efi partitions, and prioritize the default one in
the bios boot menu. Not as sophisticated as what you do, but I am
usually not running updates on the rescue system. I install the latest
fedora rawhide once a year, usually, so the rescue system is out of
support. Fine for rescue.
