The point (my point) is that at the beginning of a file it can be
only handled in a general way with some preprocessing. In the
middle of the text there should be no problems because it's under
our control (including callbacks).

The semantics of FEFF is unrelated to luatex (as typesetting
engine) and its behaviour should be decided by the format or the
user.
