I didn't know there's even such an option. But yes, it creates links 
in /boot/ now.

That's why I need those links in /boot/ , so refind would easily pick 
them up.

I thought it was obvious, but I write it again to be clear. I'm using 
LUKSv2+LVM setup and (so far) syslinux/extlinux as a bootloader in 
MBR/MS-DOS partition layout (this will change to refind + EFI soon). 
So my machine is encrypted entirely, and only the /boot/ (and future 
ESP) partition remains unencrypted. When my system creates the links 
to the initrd and kernel in / , they're useless since you have to 
decrypt the root partition in order to get to those links, and in 
order to decrypt the partition, you have to load the kernel first,
but when you load the kernel, you don't need the links anymore... So 
as you can see the better place for the links is in /boot/ and not 
in / , at least in the case of fully encrypted installation setups.
