Why doesn’t the Python package manager (PIP) have package signing feature?

I’m using the Python Package Manager (PyPi) since a very long time and I couldn’t help but notice that package signing feature isn’t there at all (According to this reddit thread, it used to be there many years ago but they removed it sometime back for some unknown reasons). That means, if I install some package by running , there is no way for me to ensure whether its the same one uploaded by the author of that package. So the user who installs my package has no way of knowing that it was me who uploaded it there.
