When adding a kernel a missing initrd should be regenerated. Similar to the option --no-reuse-initrd.
In my case I had space problems on my efi partition so I removed old kernels with zypper and also removed all folders from /boot/efi/long-random-string. I had assumed that everything needed would be regenerated with sdbootutil add-all-kernels but this time it only added the kernels without the initrds.
