Well, I managed to get the entire docking system saved now as an Item Assembly after carefully "Cutting" it out of the Alkonost. Had to check what every component is connected to and mark them as needed or un-needed if it's relevant to the docking system, and now it works. Though, to be honest, I never intended to use it with normal submarines like the Humpback or Dugong, it works best with shuttles or very fast ships really, especially the latter, as it saved a respawn shuttle-full of players a couple times just due to the docking mechanism.

Really...? Looking at the alkonost and several others that use the system, there's always a lot more components... Likely due to it including the ballast draining mechanic as well... Oh well.

Nobody forbids you to use the circuit in other works. Although I would not recommend putting auto-docking on ordinary submarines, as when docking with an outpost, an error log appears very often.
Speaking of the circuit itself, there are only two components(signal check and delay). I think this is too few to publish in the workshop.

I'm guessing it's not likely to get it's docking system as a standalone? It is rather nice to see in action and use, but quite a pain in the rear to get everything it needs just from the shuttle itself, so I could use it on another one, I.E the Selkie or the EK Gopher.

this looks like a base submurine but better
