This is why the U.S. government needs a dedicated digital team like the Obama administration had setup.
The entire government can be their clients, so they can efficiently reuse stuff they’ve developed.
The UK government has done this I believe (I’m not entirely sure how it’s setup, but I do remember them publishing a UI toolkit that didn’t just look good but covered accessibility properly), and I think every govt should be doing it going forward.
