Description of problem: In the official default sway config the terminal emulator is set to alacritty. Fedora decides to do a sed in the sway.spec to replace it with urxvt256c-ml instead of packaging the recommended terminal emulator. Packaging alacritty in Fedora and not a setting a custom terminal would give users trying out sway a better and more official experience.
You can try asking in devel.org if someone would be interested in doing the work. Since alacritty seems to be written in Rust, I think it might be good idea to CC Rust SIG (more info: https://fedoraproject.org/wiki/SIGs/Rust).
