Your interpretation of my idea is correct. I must stress they are not based on what I think is "right" they are my interpretation of how I view the clues Ridley offers in Covenant and what he has said in various interviews.
He has given the responsibility for driving the narrative to David/Michael and indeed Katherine has said this prequel trilogy is not about her it is about David.
The Engineers and Shaw (and what happened to them) in Covenant are a reaction to Davids narrative.
Ridley has indicated in the next movie that the Xeno morph will move away from being controlled by A I and be more independent of it that of course fits the continuing cascade of creator/creation. It is also dramatically crucial if you wish to grow the threat of the Xenomorph's rather than have them sharing the antagonists spot.
In order to connect with Alien we need to see :-
1) The information link with Weyland Yutani which of course can be done by a main frame link with David/Walter.
2) We need to see in Ridleys words who the Jockey is. That he will amend some of the circumstances of the ship (no cryo/pods, the burnt trap door and the who's laser are all possibilities) but the main point will be to explain what the Jockey was up to and how he got into trouble. If that is a key connective point then it is either David/Walter or, an Engineer who becomes involved in David's narrative, possibly one of redemption. Whoever the Jockey is its about David and his ending/transformation before ALIEN. He is so important to the narrative anything else does not make dramatic sense. Put it another way for a new character to enter and be the Jockey and be entirely independent of Davids narrative makes no sense just as re introducing all the bull shit (Wayne Haag) from Prometheus makes no sense other than to bring the Engineers response to Davids destruction into the narrative.
In finishing most people use plot points and devices to get to the point where they want the Jockey to be. I am looking at it from Ridleys point of view and giving it a story that the global audience would find "Cool" and like Aaron on AVP whether he likes it or not his belief is all roads lead to David.
It can all change or not get made but based on all of the evidence of David the straight line into and through Covenant and that in Ridleys view he is the originator of this version of the Black Goo outcome nothing else makes sense.
I think I have a clear view of what Ridley is up to I guessed all of Covenant with just two surprises :-
1) The Jacob death solar sales incident.
2) The complete lack of exposition over the Engineers and Shaw from their point of view rather than what we got, how they fed David's narrative.
But positionally we got what I expected.
Put simply Covenant repositioned the narrative entirely around David I expect that pre eminence to continue.
