While helping people with CORS this is one thing I have seen people use and then getting confused as to why it doesn't work. This is already documented in the cors plugin page but catching this on startup should be a better experience.
This is technically a breaking change but as browsers already reject this combination should be considered a bug fix as we adopt the browser behaviour, leading to a better experience as you now get immediate feedback on what went wrong instead of having to debug this in a browser.
