If you are planning on several y and z anyways, absolutely. On the most recent SmarterEveryDay video on encasing a Prince Rupert's drop in glass, sculptor Cal Breed talks about the moment when a process fails. He could stop there and restart, saving some time, but instead all the pressure is off, and he "makes as many mistakes as possible" for the rest of the build.
Quote is towards the end, but the whole vid is worth a watch.
Adjacent to this discussion is the "All Up Testing" concept from the Saturn era. The conservative testing strategy was to test each component individually, then put them together and test them as a system. All up eschewed this conservative approach, testing everything that was ready. It's only marginally germane to this discussion, but a great historical note since other commenters are comparing the Starship with the Saturn V.
