Well, of course it shouldn't. It should return the information that is
available, and then we can decide, based on a user setting, what we
want to do about it: the options are, at least, to treat the ligature
as atomic (the right thing to do for ligatures like %, &, and ß),
guess (possibly the right thing to do for ffi?), or refuse to use the
ligature in question and fall back to individual characters (which
isn't always possible, but it is what we do right now for ASCII
ligatures).

How so? I honestly don't think it does, because it would treat the
ligature as one glyph.
