The explainer link is a 404. Is it https://github.com/sohomdatta1/rt-explainer?

I think this should be called requestMethod or just method. (See also responseStatus.)

Also, a method can change due to redirects, but this won't pick that up.

That is the correct link, I have updated the description

Can you point me to which cases the redirect would change the method being used? Also, does this mean we should restrict this behind CORS (given that reporting a different HTTP method could be considered a leak of whether or not a redirect occurred)?
