If we go by how Bethesda treats the canon in their Elder Scrolls series, then the physical presence of aliens and their interference with the Earth is definitely canon now. Whether or not the events of Mothership Zeta took place (as in; whether or not the LW was ever abducted and went through the MZ questline) is likely going to be left ambiguous. While the quests are triggered by happening upon one of the game's easter eggs, the entire DLC seems to be far too detailed to be considered one itself.
This is based on how Bethesda has addressed the actions of the player in their past games, by introducing new elements to cover multiple endings (The Warp in the West to cover all of Daggerfall's endings), leaving the fates of certain characters ambiguous (was Vivec killed by the Nerevarine, or did he simply disappear, etc.?), and the noteable of absence of every character that the player had the potential to kill in the previous games (the exception being M'aiq, who is Bethesda's chief easter egg). Generally, the only established details of the player characters are that they completed their respective main questlines.
Generally; if something can happen it could've happened, with the lore surrounding it being definitely canon, but whether or not it did happen is not canonized. So "aliens" yes, "LW's great escape" maybe.
While Fallout is obviously a different franchise than the Elder Scrolls, the rogue-like exploration-heavy nature of Fallout 3 suggests that they intend to take the Fallout franchise in a similar direction, so it's not far-fetched to assume they'd treat what's canon in a similar way.
And yes, I'd also like a "Yes, but I sure as hell wish it wasn't" option. The conflicts in a post-apocalyptic setting should revolve around human nature in some way, but the aliens as they're written fail to do that and feel horribly juxtaposed against everything else.
