Good news, I tested my previously-described RAID1 setup and it works.

After adding the nofail option to the two ESPs and to the two swap
partitions in /etc/fstab (see
https://www.debian.org/releases/stable/amd64/release-notes/ch-information.en.html#systemd-auto-mounts-incompat
), the system is able to boot with either drive disconnected, as long
as I use the workaround [1] for the mdadm bug.

When I have time, I'll try to see what can be done in package
grub-efi-amd64 (and possibly other packages) in order to automate this
setup...
Any help will be much appreciated, of course.

I am still worried about this situation: anyone willing to share
his/her opinion on what should be done?
