discrete slurs and ties

I have learned that short slurs and ties aren't engraved manually;
instead, there are ready-to-use stamps.  In other words, since the
number of such stamps is limited, tie and slur shapes become discrete
if their length is below a certain threshold.

Do we handle this similarly?  People can argue that this is an
unnecessary limitation; lilypond can do a `better' job.  However, I'm
not sure whether we should do better...
