Well, in trad Irish music that I play...the chords are weakly attached to the music, so I can "imply" a lot! In changes from D to Bm for instance, I'll often play the low B note only, if the Bm is held for only one beat.

In bluegrass though, woe to the one who doesn't make the right chord change at the right time! No implied chords please, or you get lots of frowns from your band mates.
