This is a step in that direction. What they are proposing is not so much "no bootloader" but using a small Linux as bootloader. I'm using a similar setup for some time and it gives some of these advantages. Especially you get support for all relevant filesystems (you can support everything Linux supports because it is Linux), it can dynamically build a minimal initramfs with only the needed drivers if you want to and understands module dependencies (e.g. it can just dump the list of modules it uses itself) and is generally much more flexible.
