You could include the modules you want in grub image so you can get
tab expansion even when you got dropped to grub rescue prompt. Or
include whole bunch of modules so you can boot even without the module
directory. Some modules will be automatically included as dependency
of another module, so for example if you include "ls" then "normal"
will automatically be included

This is what I use:

grub-install --modules="all_video help cat echo ls search test
part_gpt part_msdos loopback fat ntfscomp ext2 btrfs xfs zfsinfo
iso9660 configfile linux chain boot" /dev/sda
