Hmm... it would be pretty complex, but might be a certain elegance to four pairs of gimballing Rutherfords surrounding a small number (or single) large central main engine. Rutherfords provide vernier directional control as well as landing thrust, maybe even with engine-out redundancy. And a large, non-gimbaling main engine could be easier (read: quicker) to develop....

I’m more interested in how well the thermal tiles survived that bump, personally. If they held on, that’s a really good sign that the mounting system is maturing. -

Also keep in mind that Starship can hover on a single engine, maybe two, so it’s not a full-on suicide burn. They are, however, very propellant limited right now, AFAIK these SNs cannot lift off with full tanks, no VacRaps, so that itself also greatly lowers their margins. The whole system will probably work better as, well, a whole system, including... We haven’t heard anything for a while, other than it’s been temporarily back-burnered, but SpaceX did/does have plans for hot-gas methalox RCS thrusters, which would greatly help with control during the flip. Now, hot-gas thrusters, a greater fuel load at landing ignition, and a whole bunch more flights to tweak the interactions of all of the above, now that the general concept has been proven, and things will look a lot less squirrelly. -

Initial landing burn on two, touchdown on one, because hover. This is not a concussion-induced hallucination, that actually happened. -

I can personally attest that a bit too much of that can lead to staying up all night designing crazy rockets that actually work and occasionally founding vast empires from a single city... but don’t ask how I know.... But more than likely, someone probably just told him that he couldn’t... -

Added complexity (of more plumbing) means added weight, added cost, and potentially added failure modes. There’s something to be said from simply figuring out, through trial and error, how long X part can go before it need thorough inspection or just preemptive replacement. As this was a life leader part, that sound largely like what they’re doing. They don’t want to invest too much effort here, as Starship is right around the pike, and is planned to make Falcon obsolete. The question is, where does that balance point come? -

See, now I live in a very mild, not too hot not too cold climate, and I got a heat pump specifically because it was more economical for warmth than the old electric “furnace.” The fact that I also got air conditioning out of the deal was a (very appreciated) bonus. For even more efficiency (and up front cost), you can use the ground as your heat source (even tho it’s always the same temperature a few meters down ). Or got the opposite direction, and start pumping some really massive amounts of heat, and you can liquify air.
