But this again creates confusion for some users who have to find out the "actual" prefix dir in case he/she wants to modify grub.cfg and grubenv in that dir. The only way to force grub-install to install "everything" in /boot/efi/efi/grub/ is to us
The modules and configuration files form platform-independent part as far as install is concerned (it's always handles the same way). The grub.efi is the EFI specific part which needs to go where EFI expects it. /efi directory on ESP as its name implies stores files for EFI, perhaps some small config files, it is not to store our bunch of modules. It's ok to use ESP to store modules unless they go into /efi directory but it's hard to say if such a long list of files will trigger any bugs in firmware implementation but in any case platform-independent part shouldn't go into firmware-specific directories. We've already had issues with IEEE1275 when we did something similar

The problem i have is installing both grub2 i386-pc and x86_64-efi . Both have /boot/grub as $grubdir . I use /boot/grub for all grub2-bios stuff and /boot/efi/efi/grub for all grub2-efi-x86_64 related stuff. I have not seen any issue with having modules in <UEFISYS>/efi/grub dir itself. AFAIK the modules are platform dependent since one can't use i386-pc modules in i386-efi and vice-versa. x86_64-efi is out of question since its a different arch. I guess for now doing

sed 's|/boot/grub|/boot/efi/efi/grub|g' -i grub-mkconfig

will do, until you implement the platform specific subdir idea you mentioned. Thanks for clarifying this. For me this is not an issue. But I also maintain grub2 packages in Archlinux. What should I tell the users (those who have both grub2-bios and grub2-efi-x86_64), use /boot/efi/efi/grub for everything or do the sed stuff for grub-{install,mkconfig}?

sed 's|/boot/grub|/boot/grub-efi|g' -i grub-{install,mkconfig}
