If so, it seems as if Windows is undergoing a Waylandization. "Yeah, we went ahead and removed those because they're legacy. Modern rendering pipelines don't work that way anymore." I don't WANT a rendering pipeline! I want a surface, and to make calls to scribble on it! That's it!
Very unlikely. Far too many applications depend on those things. It's more likely that they accidentally changed something subtle that happened to break colorForth.
In this specific case, I don't think the rewritten version of the document is infantilizing.
