Dude, wake up. In 1983, that was extreme. Plus, thrash is extreme. It was the first extreme metal. Thrash qualified then and it qualifies now.
Pretty debatable, actually...

I personally see grindcore as extreme metal. Grind is a special animal that is real death metal mixed with real punk. To me it is worthy, although it bares the label "core", whereas I am not a friend (generally speaking) of (90's style) hardcore and metalcore.
Thrash is mostly always extreme, although it predates the term. I know that Anthrax and Toxik and many other thrash bands don't really sound "extreme", but that is mostly based on the perception of the vocals and the cleaner guitar sound. Beef up those tones and nobody would be arguing.
The problem with making hypotheticals is convincing yourself that they're not true once you start making them. The bands you listed may have "nobody arguing" IF they did what you say (probably wouldn't to be honest), but since they don't do said things, they aren't "extreme metal." Doom is hardly ever extreme, but certain styles of it (funeral doom, etc. but not true doom) are extreme enough.
I think the vocals are a significant factor in a band's extremity, because extremity is largely an aesthetic thing and the vocals contribute significantly to the aesthetic.Indeed, grindcore is not extreme metal mainly because it's not technically a genre of metal (though recently it's been kind of accepted as one to great extent). Thrash can be extreme or not. German thrash is very extreme, as is a band like Dark Angel. Even early Metallica isn't very extreme, but I think it's opinion.
.When I think extreme metal I think death, black, grindcore and doom metal with harsh vocals.
