If we don't need the method info to be hidden when opaque, you may also want to add it to https://fetch.spec.whatwg.org/#create-an-opaque-timing-info.

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

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.

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)?
