I recently switched to using a unified kernel image on my laptop - a UEFI executable that includes the kernel and the initial RAM disk. It is loaded directly by the UEFI firmware, hence no boot loader is needed anymore.
I'm still resolving a few issues, but it's essentially working. For now, at least, I've decided to use dracut to generate the initramfs image, and the Arch Linux dracut-ukify package to automate creation of the unified kernel image.
