Software engineer here who works on web services. Most production-critical things in our workplace aren’t managed by GUI’s, or command lines… but by code. There are usually some infrastructure-as-code tools involved, like Terraform, CDK or Pulumi.
GUI’s are often reserved for quick fixes and trying out things on staging servers (derisively called “click-ops”).
Nice - having tried wvkbd I would agree. How did you plan to use gnome’s vkb without gnome?
