So then the maintenance overhead goes up, as you can always replace \EFI\FreeBSD\ bits, but you need to make sure \EFI\BOOT components are actually 100% without-a-doubt yours before you replace them. I'd be in favor of installing to \EFI\BOOT\... as well if and only if the file doesn't already exist, assuming we can figure out how to make it not a maintenance nightmare -- which I suspect would just mean that we have some tool that users use to update the ESP rather than instructing them to examine/replace files manually.
