That makes me wonder if there is still a reason to have the rear facing seats blocked off.
I haven't measured, but I'm fairly sure that there's a good metre between faces when you sit at the tables on the StreetDecks and the E400s. If that is the case, then the 1m+ guidance can still be followed sitting face to face at a table.
