| Mr. McB,
The "leave it to the bass player" philosophy works when you're playing certain styles, and some bands do it that way, but you'll never hear them mentioned for their musicianship. X/Y chords are meant to be read by both the guitarist and the bassist, if both are supposed to be playing at that point in the music. Again, to not do it that way is sometimes acceptable, but if you like things to sound "crisp," both players should be contributing to proper voicing.
