There are quite a few UX problems with nix profile. I'd like to document them to give some context:

• nix profile pins nixpkgs per package #7964
• nix profiles are hard to reproduce #7965
• nix profile: match entries using flake uri #10064
• nix profile stores a 'resolved' source attribute #10077
• nix allows duplicate binaries even for different packages under certain conditions #9801
• More concise nix profile list #10098
• Show package priority in nix profile list #9802
• nix profile upgrade should warn the user if the flake is pinned #8704
• nix profile remove '.*' doesn't remove path installabes #7487
• nix profile cannot intuitively upgrade all packages #10162
• nix profile counter-intuitively uses regexp to match packages #7962
• "nix profile" allows installing duplicate packages #5587
• 'nix profile' has terrible experience upgrading packages #7530
• nix profiles upgrade and remove have counter-intuitive argument #7960
• nix profile subcommands rely on index identifier #7961
• nix profile: Allow referring to elements by human-readable name #8678

I thought I'd gather them here in a single overarching issue, instead of listing the problems all here.
