I do not subscribe to this point of view. Distributions used to handle 
multiple boot sectors, why could they not handle multiple EFI partitions 
as well ?

I really don't think the system manager - be it yast, 
yum, apt, whatever - is capable of even trying.

yum and apt are package managers, not system managers. FWIW, Ubuntu's 
grub-efi packages can deal with multiple EFI partitions in the same way 
grub-pc can deal with multiple boot sectors.

At the end of the day, it's down to the user, and if you can shove a 
quick rsync in the initramfs or boot sequence to sync EFIs, then that's 
probably the best place. Then it doesn't get missed ...

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