Yes, I'm using it without major problems for months now.

The layout I have is as follows (where /boot/efi is my UEFI system partition):
/boot/efi/EFI/arch/vmlinuz-linux.efi
/boot/efi/EFI/arch/initramfs-linux.img
/boot/efi/EFI/arch/initramfs-linux-fallback.img
/boot/efi/EFI/gummiboot/gummiboot.efi
/boot/efi/loader/loader.conf
/boot/efi/loader/entries/arch.conf
/boot/efi/loader/entries/arch-fallback.conf

And loader/entries/arch.conf reads as follows:
title   Arch Linux
linux   /EFI/arch/vmlinuz-linux.efi
initrd  /EFI/arch/initramfs-linux.img
options root=UUID=<UUID of root fs> rootfstype=ext4 ro quiet

To automatically copy newly installed kernels and gummiboot loaders,
have a look at these links:
https://wiki.archlinux.org/index.php/UEFI_Bootloaders#Systemd
https://wiki.archlinux.org/index.php/Gummiboot#Automatic_copy_on_update

HTH!

Best,
