I hear you, and yet DDG takes this to the extreme by maintaining completely separate frontends for those who don't want to run JS or want to sidestep the getting-started hand-holding (https://html.duckduckgo.com/html and https://start.duckduckgo.com/ respectively; while digging into that, I also learned they have https://lite.duckduckgo.com/lite too for whatever that does)

So a hypothetical expert.ddg.gg wouldn't be out of character for them

I am aware that there is a slight nuance here between what one may consider just theming of the frontend versus potentially changing how query syntax works, but I just wanted to point out that DDG has embraced UX-flags-via-domain-name which would be in-your-face different from some secret toggle on a settings page
