Sure.
I think that having LilyPond guess what final barline to use, with the
ability to override this decision just by typing desired bar command
at appropriate place, fulfills this requirement.

Um, is this a rhetoric question?
A style sheet is a lilypond file with context definitions that is
included into other lilypond file to affect how the latter is
formatted.

ok, good point; replace that with:
if the music is more than 3 bars long, use a final barline; if it's 3
or less use a regular barline.  That's 100% predictable, i think.
