Was anyone present at the time and can remember when and why this decision was revoked?
It was “undone” pretty much immediately because people misunderstood what “focusing on documentation and recommending to newcomers” meant.
Additionally, the announcement was done during a documentation hackfest before having any resources available to ensure that the documentation, examples, tutorials, and so on were going to be written and updated.
While that statement isn’t really true, the rollback had nothing to do with technical reasons, and more with a mismanaged perception and the lack of resources.
That particular announcement, alongside the GTK4 development announcement, are the reason why we don’t delegate press releases to hackfest participants any more.
