I'm disappointed by their choice in site design and I'm sure it'll be infuriating to interact with for those with disabilities. It's a real wasted opportunity to use this instead of something more battle tested and fit for purpose such as the design used by the gov.uk site. https://www.gov.uk/ https://www.gov.uk/guidance/government-design-principles/
I'm not sure what I'm supposed to get from looking at gov.uk. For me, it was a negative experience, and I'm glad it's not used in the US.
Accessible design is good design. Everything we build should be as inclusive, legible and readable as possible. If we have to sacrifice elegance - so be it. We’re building for needs, not audiences. We’re designing for the whole country, not just the ones who are used to using the web. The people who most need our services are often the people who find them hardest to use. Let’s think about those people from the start.

In my personal experience however, using gov.uk has being a mostly pleasant experience and don't much care for opinionated "elegant" design.
