alt Hacker NewsOn the web, keyboard accessible web UIs are a WCAG 2.1.1 level A requirement - that's literally the most basic level of accessibility standard (unless you count 'failed' as a level). If your website / web app isn't achieving that then you haven't tried very hard.
Keyboard driven, and keyboard accessible are not the same thing.
I’ve made a web application at work able to be keyboard driven one time and exactly 0 users out of thousands made use of it. People just don’t want to pay the upfront cost. In the old TUI days it was the only way to use something so you had no choice.
To be completely keyboard inaccessible I’d argue that you almost have to try and achieve it.
