Python Classroom Lab help needed: proj-data is suddenly 569M

Hello, when debugging an unexpected significant file size grow of the Python Classroom Lab [1], I've realized the following package changes since Fedora 33: proj -proj-datumgrid +proj-data-at +proj-data-au +proj-data-be +proj-data-br +proj-data-ca +proj-data-ch +proj-data-de +proj-data-dk +proj-data-es +proj-data-eur +proj-data-fi +proj-data-fo +proj-data-fr +proj-data-is +proj-data-jp +proj-data-nc +proj-data-nl +proj-data-nz +proj-data-pt +proj-data-se +proj-data-sk +proj-data-uk +proj-data-us And /usr/share/proj is huge: [fedora-34]$ du -h /usr/share/proj 569M /usr/share/proj [fedora-33]$ du -h /usr/share/proj 14M /usr/share/proj When I attempt to remove proj, I get: =============================================================================== Package Arch Version

brings in proj is: python3-scikit-image (from @python-science) requires python3-networkx which recommends python3-gdal which requires proj. My questions are: 1) What happens if I keep proj but remove the data? Or should I remove gdal entirely instead? 2) Why so sudden growth? Thanks for help.
