I am not sure what you mean with the repo archive being outdated, the latest commit was 30 minutes ago. Could you please tell us more what apps you are referring to and in what way you find the repo archive being outdated? Might be easier to answer your question that way.
Also bear in mind that its quite common for stable releases to be some time apart from each other. Florisboard for example had its latest release over a year ago, but is being actively maintained.
If you’re arch-curious but want something more opinionated and out-of-the-box, you could have a look at manjaro. It gets much shit thrown its way because its both try-hard (being arch based) and simultaneously “just works”, but that’s mostly memes
Its like the C of web, it’ll be a hundred years to kill it
