Backloading the combination gives almost 2 points of an advantage, and its not like Trusova habitually misses that combination, she and Shcherbakova have both been backloading it for years and have rarely missed that badly on it. And if you look at my post from yesterday about Shcherbakova and Tuktamysheva's SP BV comparison, having that backloaded combination eats away at the BV advantage of the triple axel. And while yes Trusova does have the ability to throw a lot of quads, she's rarely shown the ability to be completely clean on it, so she still needs to perform the SP to set herself up to not need to do all those quads to win/podium. If she starts routinely missing the combination in the SP then yes they should move it. Given how competitive Russian ladies is, if someone wants to win I don't think they can really afford to sacrifice any points on the table - if she can reliably backload the combination in the SP and get 2 extra points then she needs to be doing that - I would say the same thing for any other skater as well.
