It was from a time where there still was an existing steering committee and I was in it and there the decision was made and then the decision was told to the public, probably in some post on garagegames.com.
Well creating stuff only makes sense if people know about it and use it or at least mention that it exists, which did not happen, instead people ignore that the steering committee existed, ignore all plans and decisions that were made and the things that were done and pretended nothing ever existed.
No it is not just as good as having it in the main repo, because nobody will know about it, when nobody mentions it, because they actively ignore the decisions that were made and keep going like before, like no decisions were ever made.
That is similar to the new repository now, new people will still go to the garagegames official repository and notice it is inactive and conclude no progress is made and if you tell them, well there is progress made, in this secret new repo, that nobody knows about and nobody tells you about, but there is no problem with that, because it exists, somewhere. You have to do actual public relations to tell people that it is different now or at least announce it somewhere on a front page or blog, which currently do not even exist and update all the links and references from the old unused links to the new used links.
So there is a crucial difference and things existing somewhere is certainly nowhere as good as things existing officially and were officially announced as the new standard now.
Have you never watched statistics on websites? Do you know what conversion rate is in business? Do you know what bounce rate is in analytics?
Let me tell you how it works, basically we are a business and when new potential customers come here, they will just look what is obviously there and if they see an inactive website, with no news made for years and nothing done in the official repo, they will conclude it is dead and leave. Most people will and cannot bother to research every small corner of the website, forum, Github to see if someone somewhere mentioned where the actual stuff is happening. People search for an engine and come out to some social media page and see it was not updated since forever, they conclude it is dead and use another engine, customer lost, having activity and updates somewhere else does not matter in the slightest anymore, it is a difference like day and night. In the day things are visible and in the night not, of course maybe 1% of people will also find things in the night, but 99% will not bother.
