So early death metal is closer to "ten minute songs that drone onward"? Let's face it, death metal barely has any real definition at all. It's a convenient catch-all that has been filled with everything from the earliest extreme thrash bands to modern-day tech-wank. You place funeral doom under it. Other people place Gothenburg's output under it. People put basically anything that came from Florida or any other kind of tech-thrash with harsh vocals (hello, Spheres, Thresholds, and The Human Abstract) as death metal. Some people actually think that Cynic, Opeth, and Supuration are death metal bands. If doom metal is unable to accommodate Skepticism, death metal sure as hell cannot and be considered a meaningful sub-genre.
