Why not use Lilo instead ? It's simple, reliable & adequate for most installations.
I've never used anything else in 20 years of Linux, including 17 years of Gentoo.

LILO has never supported UEFI, ELILO is abandonware and generally isn't signed to be secure boot enabled (ditto for gummiboot/systemd-boot). If you want UEFI secure boot, shim + grub2 is the only game in down that works out of the box for the major distros.

I generally stay as far as possible from UEFI and where I have a choice of bootloader I like syslinux. Grub seemed like (was) a great advance on LILO in many ways but Grub2 is a huge confusing mess.

I wish I'd read this article before updating practically all my grub booting servers (CentOS 7 and Debian 10)! Here's hoping there's a fix that can be applied before any reboots are required...

Does it provide TPM2 measurements and signature verification of boot artefacts?

There's no reason to use Lilo on a UEFI system; you get exactly the same user interface by using an EFI-stub kernel (with a built-in command line to set rootfs) and the BIOS' boot menu, except there's one less part to forget to update.

Plus you get the ability to use an EFI shell to do all sorts of repair work before the OS even gets started. (Sure, the stuff in an EFI shell is mostly useless *until you need it*, but then it is crucial). There is no such thing as a lilo shell!
