4/4
There have been cases in the past where #Unity has bought out third party paid assets and made them an official free part of the engine (most notably #TextMeshPro and #ProBuilder) but it has been many years and my hope that they would do this for #OdinInspector is gone.
Honestly as a long time user and being #selftaught, I could go on and on about Unity and their questionable decisions over the years, but I'll close this #rant here for now.
