That’s not always the case. Feedback comes from the people that use the documentation for the first time, as well as people who use it every day; all feedback gets weighted and included into the changes.
In many cases, though, people who use a bad website every day and develop workarounds end up resenting any change that makes things better for others, because now they have to adapt. It’s a fact of life.
That’s why there’s a whole client-side search mechanism.
Devhelp 41 will be released next week, and it works with the gi-docgen-based references.
In the future, the Devhelp app will also see additional changes—especially when it comes to searching. Those are planned for GNOME 42.
