none of the buttons on the steering wheel lack well-lit counterparts elsewhere on the dash and console...if you can't remember which of the 6 buttons on the steering wheel does what you want, look around...the alternate buttons/knobs aren't too far away...though the steering wheel buttons are definitely the most convenient.

i like accent lighting personally...i think it would look nice. everyone had their own opinion obviously, some find it annoying, some find it useful, some find it just looks nice but not necessary, some don't even know what the steering wheel buttons do in the first place (nobody on this forum, of course)
