25-50MB would have been the /boot/ partition size recommendation around 30 years
ago. For an ESP, I don't think I've ever seen a recommendation of less than 100MB.
Some bootloaders newer than Grub2 are dubiously designed to load kernels & initrds
from the (FAT!?!?!!!! — no symlinks possible!) ESP, leading to vastly larger ESP
size recommendations.
I created this one 7 years ago:
# df -h | grep boot
/dev/sda1 320M 21M 299M 7% /boot/efi
#
At that time, ESP minimum was 100M, unless using 4k sectors on a boot disk larger
than 16T, in which case it was 260M.
