I think Scott Manley's position on the "still hasn't gotten to orbit" take is probably still the best and most accurate:

What Scott is missing is that the only reason "it did not get to orbit" is of interest at all is that SpaceX keeps claiming they got to orbit with starship. I believe that the trajectories have all been suborbital by design, but it still pisses me off that they keep claiming they got to orbit.

The reason this matters is that if they get into an orbit in a short test, they need to exit that orbit with some sort of active system. So the statement "we got to orbit" implies a lot more technology development than the current flights actually show. I agree with Scott that Starship can easily enter LEO, but I am not so sure it can exit gracefully.

What exactly do you think is the “more technology development than the current flights actually show“ needed to get into and out of orbit?

My impression is they just need to leave the engines on a little longer to get to orbit, then turn them on again with the ship pointed in another direction to get back to the suborbital trajectory they’ve already demonstrated deorbiting from.

The hard part is reentering through the atmosphere without burning up, flipping, and landing, which they’ve already demonstrated multiple times. There’s no additional atmosphere between where they’ve flown and “orbit”.

A little more longevity and one more engine restart, unless the suborbital is very suborbital, then it also means a lot more delta v. It doesn't seem that far away at all.

They tested that extra restart as part of today's flight. I think the only thing now missing is carrying the extra fuel.
