This isn't that much of a problem because I and probably many others start the wg-quick script as a system service. But when you run the script as non-root, it asks for sudo with the option "-p".
I have my doas symlinked to sudo so the script actually runs "doas -p prompt" in which the option not exist in doas. I found a the script for openbsd from your repositories, I looked at it and it uses doas. It's not that important but it'll be nice if you could add doas to the linux script.
