Regarding the rabbit hole, the internet connection and privileges were
required for running this script in the first place. I only suggest giving
the developer - perhaps not a software engineer at all - an easy way not to
require the (possibly inexperienced) user to do it manually.
Put it another way, you a copy-pasted code from SO is not needed to use
only stdlib now.
