This was true even for the Fraktur style which, unlike the Antiqua style
that replaced it
for modern German did have the concept of *required* ligatures as well.
(And the numbers
of optional ligatures include many that we might rarely encounter in a
modern non-decorative
font).
The archives of this list give many examples of compound words where the
precise location
of the compound elements need to be known to determine the meaning of
the word. As
Adam point out, German orthographic practice (and I use this term
deliberately, even though
the effect is only visible when text is typeset) is to use the presence
of ligatures to mark the
*absence* of such a a boundary. In other words, you never ligate across
such a boundary
as it would mislead the reader.
(Unlike Fraktur, leaving out all ligatures is OK, but in its own way,
perhaps not the best typography).

Technology should exist to support the way people write, not the other
way around. Given
that, a font that is acceptable for German would look good both when
showing an unconnected
f and l, as well as when showing a ligature - both will be needed.
Creating outlines that fudge
the issue by making overlapping glyphs look (nearly) indistinguishable
from a ligature is
a cute trick for English and other languages, were ligatures are
permissible in any position
in any word, but not ideal for languages like German where that is not
the case, and where
a distinct appearance of ligated and not ligated pairs is desired.
Whether or not you consider the occasional use of separate f and l
something that is
aesthetically pleasing is besides the point: first and foremost it is
correct usage according
to the orthography of the language in question (and is a prescription
that has managed to
survive a rather drastic change in typographical style).
Now, once you've accepted that as a legitimate requirement, as an
implementer you can
start to figure out how to get the aesthetics back into the picture. I'm
not a type designer,
but I sense a certain anglocentricity in the designs that originate with
or are distributed by
large US software houses. So I would be surprised to see that you find
good guidance
there. Perhaps there are suitable examples from the time of hot metal
typography that
you could study.

Having the rendering system enforce Scandinavian orthographic
preference? I think that's
going a bit too far. That belongs not in the rendering system, but in
the spell checker.

The use of long and short s, when the long s was still used, in German
follows similar rules
as the ligatures. Use of the short s was required not only for any s at
the end of a word, but
also at the end of an element in a compound word; it is for this and
similar reasons, that the
choice between long s and short s cannot be delegated to the rendering
system or the font.
