?!! ouch ... seems orthogonal to the actual important parts.
Disclaimer: I didn't try it.
I like the idea, but I don't think it should be on by default. The rest of us have just used root-specific shell prompts for the last few decades or so.
Not every software needs to be infinitely configurable and open source just in case the configurations don't cover the needs of all.
We need opinionated software, if you don't want to make any choice for me, you can't even give me an assembly editor for fear of forcing your CPU arch of choice.
Whenever I hear someone describe their software as "opinionated," I have found what that usually means is that the developer thinks they are smarter than everyone else and all of the unfriendly attitude that usually comes along with that.
Whoever made the decision that run0 should turn your terminal red by default doesn't understand that there are practically infinite terminal configurations out there that this will interfere with or be outright incompatible with. My argument is that the decision comes from a place of ignorance of the sheer diversity of the users of the software, not from a place of, "we are so smart, and are the first ones to think of this feature."
