Yes, you'll find that with a lot of beginner patterns for baby sweaters. I just finished one that was all squares and rectangles, no shaping at all. This pattern is a crocheted one, but they do have a knitted version of this. They sound crazy, but they really do work once you get them all seamed. If you scroll down to the bottom of this pattern, you'll see the shapes with this. The shoulder seams are sewn together. Stitches are picked up around the neck for the neckline rib. Then stitches are picked up along the edges for the buttonholes. These are great sweaters for the type of cables you're doing. It's just straight knitting with no shaping or having to worry about keeping in pattern.
