Crush is probably realizing that without character sheet data it's much harder to do character development. I would find it hard to ramp up intensity in a visual novel with a character if I didn't somehow plot how their corruption is advancing, and what boundaries are being eroded and what desires are becoming stronger etc. essentially the writer would have their own character sheet that no one sees except the writer. If he managed to bring back the lifepath and add effects to the character he could potentially have more of a framework with which to write the sex scenes in. But it really depends if this slows him down or speeds up updates (for crush i'd say slow down).
Ideally a writer will want to finish a whole game with the corruption path in mind. And then go back to the beginning and basically start the next branching route - not a prude route that would be dumb - but maybe there would be a female agent fallen/submissive route, and a female agent femme fatale route, and a female agent bimbo route or something like this. So you write the fallen route first with dice rolls/character sheet that work for that. Then go the femme fatale route next.
For some reason game devs try and do them all at once and imo it's harder to keep track of, takes focus off of doing one thing, and extends update times by double or triple so there is less game to play with longer waiting periods.
