I'm not criticising the jumpsuits, I actually liked that idea. They were functional but distinctly Earth tech, complete with pockets and visible zippers (no magical 23rd century invisible closings). It's more the fact that the division colour was on the shoulders in the same way that it was for
DS9 and voyager, in the same shape as it was for everything from
TNG to Nemesis. Add to that the rank pips in the same style as
TNG onwards. It was just another example of them trying to echo the design of the later shows rather than TOS.
