Different instruments have such different traditions for how to make sense of the same markings. I prefer to indicate the sound I'm looking for and let the players figure out how to produce it. Maybe because I'm a former #trombone player: no one is expected to know how exactly a trombonist produces a legato articulation, but when you ask for legato, we do it. For strings, it's more like each marking calls for a specific technique, and #composers are supposed to know them all.
