I do not think this has been in serious dispute in the last 50 years. This paper just puts a more precise date on the settlement in Newfoundland that was already well known.
As a Danish person it’s sort of interesting to see how much focus this particular area gets in comparison to other Norse history, but no, it hasn’t really been disputed in any serious manner for a while.
A lot of the evidence doesn’t really prove anything. The map turned out to be a forgery, and wood having been worked by metal tools could have happened through trade.
L’anse aux Meadows is a Norse settlement similar to those found in Greenland, however, and that’s sort of the evidence you need.
This is the only settlement found however, and it may never have had contact with the indigenous people considering how isolated it was. The “vikings” weren’t there to raid, they were there to find some decent farmland, and if that’s what they found, they could have died out without anyone knowing about it until a thousand years later.
