No, these are not adequate places. Too early or too late. The right place is when anything is written to the EFI partition

these ARE adequate places and a "too late" simp,y can't exist - after the package transistion /efi/ should be rsynced to /efi-bk/

Using only Debian-based distributions and GRUB, I confess that I know very little about other distributions and boot loaders such as Red Hat and systemd-boot. In Debian, package upgrades do not happen during the boot sequence, so waiting for the next boot to sync EFI partitions implies that they will be out of sync when the boot loader is run at the next boot, possibly breaking the boot sequence.

Quoting:
"with uefi you can no longer have everything needed for boot on a RAID"

AFAIK, that was never possible with legacy BIOS boot either. The MBR and GRUB core image were outside RAID.
