Wait. What the hell are you going to do with those afterwards? Again, there's a shitload of filesystems that cannot be exported over NFS, exactly because there's no way to implement sanely working fhandles. And idiotify is allowed for all of them.
You *can't* decode anything fhandle-like on e.g. sysfs. Or procfs. Or configfs. Or any network filesystem (I'd argue that we should simply ban idiotify on those, but good luck doing that). You *can* do that for FAT derivatives, but only if you have parent directory when creating that sucker.
