My point was, systemd is not the only init system, there are others. Just because it's used by over 90% of the Linux distros out there, doesn't mean it's the only one, thus offering a solution that is tied to systemd is not exactly a solution. Grub already has it figured out, why complicate things further.
I have no desire to engage with an objectively incorrect view. However, you are the second person to mention refind which I am unfamiliar with and I'm intrigued.
systemd-boot is GRUB but without customization and fewer supported features (LLVM root etc). What more is there to say?
rEFInd is (as the name implies) an EFI bootloader that, on every boot, scans all attached storage devices for a bootable partition and presents all those found in a boot menu with a quite nice graphical theme
