Apparently UEFI firmware can hanlde ESP on RAID thus booting failed.

You probably mean "can not".

Do not forget that you need to use metadata version 0.9 or 1.0. And default is
1.2. 1.1 and 1.2 place metadata at the beginning of device so firmware does not
find filesystem. I tested booting from ESP on Linux MD RAID1 and it worked just
fine, but I think something got confused (grub2-install or perl-bootloader).

The main problem with this is - you cannot prevent writing to ESP while in
firmware, which in case of RAID1 leads to filesystem corruption. So I would
really prefer two independent ESPs on different disks and manual
synchronization by perl-bootloader (after all we just need to copy couple of
files).
