Yes, it assumes that nobody wants to change display dimensions or industrial design.

This interface mingle-mangle could IMHO be solved, but would require some years of intensive work with the industrial standardization bodies...

Yes their main claim or starting point, that devices are not designed for durability is not bad attitude of the manufacturers, but the result of a balanced tradeoff between two customer requirements: better-than-last-year *and* cheaper.
But their video is a well done sketch of the idea. We need such guys who know how to visually present things...
