I didn't mean to imply priority: a clash is just a clash, not a sign that either project isn't entitled to the name. It's just an unfortunate namespace problem: language package managers (overwhelmingly) flatten things into a single-level namespace, and so we end up with things like this.

I work on a graphical tool that visualizes x86 binaries! It uses iced (the decoder), and it could very easily end up using iced (the GUI library).
