Like old jazz tunes. ^
Besides keeping the bass or kick drums centered, I don't pan any drum/perc sound more than 15%, usually it's under 10%. I always think of a live drummer too and try to create that "image", as if the listener were to be in a room with said drummer in my tracks.
There are of course no absolutes and everything depends on its context (unless you're gonna cut vinyl or have other technical limits) so, if it works for your track, it works.
Do it your way, because everyone else is just weird.
