So I’m a rank beginner when it comes to classical guitar, but in the world of bass guitar, sympathetic vibrations are to be avoided.

Should I be focusing on trying to prevent it, or is it just a function of the instrument that should be embraced?

I know that on the double bass, sympathetic vibrations can make it really easy to tell if your intonation is spot on (hit the E perfectly on the D string, and watch that low E start to shake).
