It's not entirely true. While it's a good idea to put kernels onto the
ESP, you don#t have to. You can also put them into the XBOOTLDR
partition.

sd-boot itsef must be installed into the ESP, but it will discover
boot menu items on both the ESP and on XBOOTLDR and combine them.

XBOOTLDR is supposed to be used only if you have an existing ESP that
is too small to carry kernels, and you'd rather not resize it.

XBOOTLDR should be vfat too, as with sd-boot you still need an fs the
firmware can read.
