Well, there's practicality and there's aesthetics and they're often in conflict with each other...
A couple of things...
The solution shown in the video makes the Strat look like a Columbus copy, circa 1976 (and that isn't intended as a compliment).
It won't work for a neck with a 22nd fret extension (though they often have the headstock end recessed adjuster anyway).
The "bullet" truss rod adjuster used between about 1972 and 1982, was
hideous. I had a new Strat (bought in 1975) with all those changes that CBS/Fender had made (there were plenty of other design changes incorporated) and I was never satisfied with it. Compared to a pre-CBS guitar it was just a copy. I sold it in 1978 and bought a Gretsch instead ( I already had a Marvin). I know that some players take a different view, but what I wanted (and still want today) is a guitar like the one Hank was using in (say) "The Young Ones" with no compromises. Just having the same name on it isn't enough. I now have two 1962 Vintage Reissue Stratocasters in FR and the rods never need adjustment
anyway.
The modern idea of the recessed headstock-end adjuster is a nice compromise. I have a USA Telecaster with that arrangement. It works - on a maple-fretboard - because the recess is hardly bigger than the traditional walnut plug. But rosewood necks with this arrangement look all wrong.
Perhaps a small section of pickguard material covering the gap might make the guitar look less like a Columbus or Kimbara?
