I can't speak to how the extent compares as I don't use Python nearly as much as R, but it is an issue. In some ways it may be worse, as there are a much wider variety of packages available for R from many different authors, so it isn't unheard of for packages to not be available for newer versions of R. That said, many of those tend to be niche, and I haven't really had old files need any kind of major revision.
