It also helps with reducing dependency distribution issues - I've written single-file Python programs using just the stdlib, sometimes of a really old Python3 version. It's really nice to just `scp` the script to a bunch of remote devices and have everything work out-of-the-box. Of course, PyInstaller can solve dependency distribution issues - but I've sometimes ran into packages that don't play well with PyInstaller (uwsgi, for example, because it's basically a C program distributed using pip, so PyInstaller can't figure out how to bundle it).
