The problem is open source. I generally agree with your analysis of the migration path, but who’s going to go through every open source library and do this grunt work? It comes at a huge cost however you swing it, and it’s not theoretical: I recall trying to switch to Python 3 over and over during those dark years only to find an essential library couldn’t support it.
