I guess I see your point - I just don't see how the Marvel Universe can be considered as separate from the Timely one when characters from the latter show up in the former all the time, are remembered as taking place in the past of the MU, and are an important part of the Stan-Steve-and-Jack-era continuity.
I would argue that Blonde Phantom's GA adventures ARE in-continuity, because when she was reintroduced in 'She-Hulk', they were specifically referred to as such. 'Remember the Blonde Phantom? Had adventures back in the '40's? Well, that's me!' Given that there haven't been any other '40's-era BP stories to retcon away the previous ones - well, there was one where she was briefly a member of the All-Winners Squad, but that doesn't directly contradict anything - I'd say that makes them, if not directly in continuity, certainly not necessarily OUT of continuity.
Perhaps a better way of phrasing it would be 'in the Marvel Era' or something like that, if 'from a starting point of 1961' is part of your criteria.
