After checking, genkernel copies only some modules into the initramfs,
unless the --all-ramdisk-modules flag is used.

Concerning the rest of your reply: thank you so much, it really helped
me a lot!

Could you suggest any reference about how an initramfs can help making
it easier to identify the correct root filesystem? Does this
functionality overlap with what grub can do, or is something
different?

Thank you,
