You have to tell people to enable full command-line logging anyway
That's why I suggested making the full commandline the default a few months ago. It is bad enough that people have to enable "normal" output explicitely.
I mean, OK... if someone absolutely does not want to see the compiler messages, I can even understand why someone would want beautified messages (although you don't need to read them if you don't want...), and they're handy for jumping to an error line, too.
But if you give them the ability to copy the beautified messages, then people will really do so.
As people post "Compiling foo.cpp" now when asking for help building something, they will now post beautified error messages. I don't think that is any good.
