I've seen a closely related but marginally more cursed unit. When I was taking a propulsion systems class in college I was reading a spec sheet for a high-bypass commercial turbofan (I think it was a variant of the CFM LEAP, but I can't remember) to compare real-life performance to what I had calculated based on some known values. I kept being off by an order of magnitude and it was driving me nuts, until I realized that the table was giving me the thrust in dekanewtons (daN). Which is basically kgf if you accept that g=10, which is apparently what the manufacturer did.

I'm glad you mentioned these two things that I've been saying for years, hotter ambient temperatures cause solid propellant to burn faster (as much as 25-30%) that increases chamber pressure and that the nozzle end of the motor needs to fail first. When screwing on end closures the forward bulkhead end should be screwed in all the way and the nozzle end can be a thread or two out (some people do it just the opposite). On bolted motors, the nozzle end should have fewer bolts. On our 12" diameter solid motors, we bolted the divergent cone on the exterior with the throat smaller in diameter than the inserted divergent cone so that if it blows, the throat effectively increases in area as much as 50% decreasing chamber pressure. We've never lost a forward bulkhead doing these things.

If you are concerned with thrust-to-weight ratios, I’d argue it’s more intuitive to describe thrust in terms of lbf or kgf (or tons, on the larger scale). It makes the comparison to the mass of the vehicle easier. Same goes for buoyant forces in maritime engineering. There’s no one correct unit for all applications.

I found the video both funny and informative. In particular the bit about the three degree cant being the difference between success and failure was something I hadn't heard anywhere else. The one thing I would have liked to have seen would have been a discussion on the effect of altitude on the effectiveness of the nozzle. While it may only add 20% to the efficiency of the rocket at or near sea level, I suspect that as you climb out of the atmosphere the sideways expansion of the rocket plume will increase enough to noticeably degrade the performance of a rocket that has lost its nozzle.
