Furthermore, both
[https://reviews.freebsd.org/D28897](https://reviews.freebsd.org/D28897) and
[https://wiki.freebsd.org/UEFI](https://wiki.freebsd.org/UEFI) — “Create the
ESP as a 40MB FAT32 filesystem to maximize compatibility” — were intended to
achieve that stated goal.

Most Linux distributions, Windows, and even Intel-based macOS systems also use
FAT32 for their EFI partitions.
