There is, since you’d be be able to resize the video element in a media query triggered by the size of the video element. If we really wanted it, we can of course insert some explicit rule to break the loop, but this design doesn’t feel particularly clean to me.

We already have dppx (Dots Per PiXels) for the resolution MQ, to query the number of physical pixels in a css pixels, so I don’t think dpx is a name I’d recommend.

As for physical units for lengths, coming from mostly anyone else, I’d probably reply with the usual story about why this is misguided, but as you know all these already, I am curious as to why you think this is a potentially good idea.
