Since when do multiple engines gimbal to create roll?!?

[Starwhip]

I was launching a career Duna science harvester when I realized that the capsule alone on the launcher could not possibly roll the entire craft like it was. I had no RCS or Reaction Wheels (Which came to haunt me when the Gyro Kraken decided to focus it's powers on the craft for the ENTIRE MISSION ). I snapped this screenshot:

Kind of hard to see, but the engines are gimballing to roll the craft. I've never noticed this before.

When was this added?

Interesting. This should help greatly with my lifter designing.

Also noteworthy is that the four-nozzle 3.75m engine and the RAPIER can provide roll authority with a single engine due to their multiple-nozzle design, not sure about the LFB.

Seems that it can't. Not sure why not since two gimballing engines on a bicoupler can.

maybe they are modeled as a single engine rather than 4 individual engines?

The LFB is the 2 engined one. The 4 engined S3 KS-25x4 Engine Cluster can control roll, but the LFB KR-1x2 can't. the uncertainty is why Squad chose not to give it the option when they did the other multi nozzeled gimballed engines.
