The only gcov-related change listed in the 4.9, 5 and 6 release notes is the addition of a new tool, so I wouldn't expect there to be meaningful changes. Regardless, I think the author's conclusion is overly specific and really should have just been "trying all of the various tools for doing something is useful even if they're theoretically comparable".
