Just checked on a fresh install of Fedora 42 "custom operating system" install, so pretty minimal. Didn't even check the "standard tools" box or whatever it's called.
Installing 'pass' pulled in:
desktop-file-utils
emacs-filesystem
git-core
libpng
qrencode
qrencode-libs
Plus weak (optional) dependencies:
libwayland-client
mailcap
wl-clipboard
xdg-utils
12 packages, 5 MB download, 24 MB installed. Could be worse, could be better.
I was honestly expecting Fedora to have less than that.
