This is also one of the things that makes dev so annoying to me, but not for the reasons you specify. While in theory, it's great that L&P offers so many different possibilities and permutations, I question whether this story benefits from this many fine-tuned story branches?
I don't think it's much of an exaggeration to predict a scenario where if A,B,C choices were taken and Sophia wears the sexy dress, then Liam and Sophia have fun with Nathalie but Liam doesn't get to taste or penetrate Nathalie, but if A,C,D choices were made and not B and not sexy dress, then they have fun with Nathalie where Liam penetrates Nathalie while Nathalie munches Sophia.
The granularity with which each event can cause ripple effects and more branches, whether it be simply different dialogue within the same scenes, or different activities (i.e., more renders of the same scene) within an event, means every update and every event has multiple threads of dialogue and multiple different actions and reactions => increased development time.
While I totally agree that these fine-tuned branches are "nice to have" - very nice, in fact - elements within the VN, I have to question they are "need to have" elements. I think the story and events would be satisfying regardless of whether we got one version and not another.
It is the supposition that all of these renders and lengthy scripts are needed to tell the story that I find so grating, because the reality is all the renders and extra pages of script are only "needed" because L&P is trying to tell a huge number of different stories at the same time.
