How did I miss this? The gov.uk Service Manual recommends progressive enhancement for all their websites.
Using progressive enhancement means your users will be able to do what they need to do if any part of the stack fails. Building your service using progressive enhancement will:
- make your service more resilient
- mean your service’s most basic functionality will work and meet the core needs of the user
- improve accessibility by encouraging best practices like writing semantic markup
- help users with device or connectivity limitations to use your service
