i'm not sure i would call this a "big government initiative." this is pretty cheap, obvious stuff.
you might pull an off-the-shelf component library for a demo app or even a startup, but the value of building in-house/from-scratch in government, especially military, cannot be understated. the web ui ecosystem is rife with security risks and accessibility footguns.
it looks fine to me. it's a design system, not rocket science.
