> Are you implying that it can't be used to install Python dependencies that have c/fortran like pandas? No, they are implying that many scientific python packages and dependencies of python packages have dependencies on non-python libraries and packages written in c/c++/fortran. If you want to manage and reproducibly pin these they also need to be tracked, because otherwise you just end up with "whatever the underlying OS has installed", if you are lucky, or "compile failed" when installing the package if you aren't.
