You could make the argument that if the port was originally released that way, then it's 'authentic' enough to emulate it the same way on that particular target system. But yep, I can see why the squashed and stretched graphics would bother people, even if they match the experience on the actual hardware. The thing is, it's a bit of a slippery slope, because sooner or later you come across a case where some of the art was made on system A, and some on system B (with a different aspect ratio) to tweak or flesh out the port, or whatever. So some circles turn out perfectly round, while others are ellipsoid... and then whatcha gonna do? :) (IIRC the first Star Control suffers from this, although I could be thinking of something else here.)

100% agreed on the screenshot/video issue; that's kinda what I meant at the end of my last post. I've also discovered that Youtube respects PAR/DAR metadata, but I find it more useful to actually scale the video myself before uploading, by appropriate X/Y factors. That lets you sidestep the issues you commonly get when you leave the scaling to the YT backend/frontend, like blur and incorrect gamma... (and if your source is RGB, it's also a good idea do the YUV conversion yourself while you're at it.)
