Not for all links, no, only links that have rel=attachment. And I would
assume that on such a link, yes, perhaps a "view inline" right click option
may make sense. I wouldn't expect this to be used on anywhere near a
majority of links, but an author can already try to craft a download link --
it's just that in many cases it's either requiring them to jump through
hoops or impossible (e.g. offline apps).
