Sure, but we're talking realllllly long term here. Is there any real point in trying to write a roadmap for something more than 2 years (at least) in the future? No one has any idea what will be going on at that point; there isn't even a roadmap for an engine independent node api; and even when one is made (never mind implemented...), it will certainly not include 'drop v8' as part of it. So we're talking about some nebulous future in which something may or may not happen after another thing which may or may not happen at some point in the future. It's pointless to speculate about such obscure possibilities. V8 isn't going away any time soon.
