Friends don't let friends use grub. rEFInd is _so_ much simpler: one efi entry, one text config file in the efi partition, nothing that needs to change when the kernel updates, and no massive pile of templating and moving parts to mysteriously break dumping you at an impenetrable grub “rescue” shell.

NFS diskless was easier for me to setup when I was doing it. THe caveat was, you needed readonly root, so that meant freezing the OS, anything that needed changing was either stored in a ram disk (that you need to setup) or a per host nfs area (kinda like overlayfs, but not)
Why would you need a read-only root? Do you mean to share across multiple machines?
If you needed to update the root dir, you chrooted into it and did the (yum) update.
Pretty cool! You could also boot into an ephemeral minimal initrd that displays a selection menu instead of doing it in iPXE. That would grab the new kernel and initrd from the network and kexecs it without reboot.

Then anaconda or whatover os installer picks up and installs the OS in a PXE install sequence when there is a local disk.

Or use UKI and throw the current kernel to /efi/boot/bootx64.efi; there's plenty of solutions to sane bootloader/kernel management if you're willing to invest 15 minutes into the topic and not act like it's scary and complicated (it really is the opposite).
Grub2 is scary and complicated. Remove grub from the equation, and all the scary goes away.

or just copy the latest kernel to something like /vmlinux and /initramfs

Does zfs support error correcting instead of just finding (already) broken files? I have been waiting for such a feature for like 15 years now. Without it, zfs is just a fad and useless filesystem (all that complexity for NOTHING). ext2 for the win! still
This could be an interesting setup for booting off a NAS like Synology or QNAP. I haven't really used iSCSI, it's intimidating how much prep this takes...
iSCSI seems intentionally obscure. One of the improvements I made to NBD was invent a simple, standardized URI format so that you can specify servers easily, eg: nbdinfo nbd://server nbdcopy nbd://server:2001/ nbd+unix:///?socket=/tmp/localsock https://github.com/NetworkBlockDevice/nbd/blob/master/doc/ur...
How well does it work in environments with noticeable network latency?

The 'target' moves slow so once you learn it, it all stays relevant forever. ... And it's very, very fun.
Does it offer performance advantages over NFS root?
