If /boot is on the ESP, i.e. FAT, you won't need the ext3 module. I
suspect part of the auto-configuration setup is "load everything we
might need". It's not really an issue since the memory used by the
modules should be freed when GRUB exits.
The bloatedness is a combination of the must run everywhere defaults and
using a full bootloader when you only need a minimal boot manager. These
days, I only use GRUB on BIOS systems.
