Yes, but on the other hand it's a good reminder for everyone processing user provided files to sanity check or convert them to a canonical format in a sandboxes and resource limited process.
Given that other recent article about university students who don't know what files are, I wouldn't be surprised in the slightest if this is considered esoteric.
It is pointless, also nobody ever cares much how well a text editor can handle obscure text files (file too large, broken encoding, ....) What matters is how it handles well-formatted files, the others aren't worth opening in an editor anyways :)
