Using /boot/efi or /efi as ESP, not having kernels on fat32

[ghost]

Hi I've read the general Arch wiki in regards to recommended partitions and it says only the EFI files need to be on a FAT32 partition. FAT32 is an old filesystem and prone to corruption, I want my kernel files to be on EXT4 or BTRFS which is usually fine (Arch wiki also says it's fine) but archinstall doesn't recommend it and it seems to fail if I try to use only /boot/efi as FAT32. Is this expected?

Any help would be greatly appreciated. 🙏
