The problem is that there are no contributors interested in improving VisualScript, so it has stagnated. If interested contributors show up, they are still welcome to work on VisualScript in the form of a GDExtension. If nobody offers to do the work for free, the three options are to remove it from the engine, let it stagnate and stay unusable, or pay core contributors to work on VisualScript. The latter of which takes away time and money from other things they could be working on.
