A great many people seem to think so.
I've just ordered this promising new translation of Sir Gawain and the Green Knight for my new course "Myths of Britain" in the spring (an introduction to the major, the course looks at the literature of early England within a paninsular, transnational frame). More here when the volume arrives.
Honestly, isn't it about time a leather-jacket clad poet got his hands on the thing?
(Thanks, Jonathan Hsy, for calling my attention to its publication).
