That's more of a possibility: a station vaguely serving one terminal,
plus a "transit" to the other(s). In effect the Old-Oak-Common plan is
exactly that, except it's a transit to every terminal.

With a rather longer journey time than your typical airport transit.

Probably quicker than the walk from the Madrid airport metro station to
the low-cost check-in desks. And it took me half an hour to get from one
end of Frankfurt airport to the other, a couple of months ago.
