The downside of disc brakes is that there is now less incentive for a
shop to be sure that the wheel is true, and less of a clear indication
to the rider that their wheel is not true.

I'm curious: Assuming a disc brake wheel is out of true only in the
lateral direction (i.e. not radial direction), what's the disadvantage
to a little imperfection?

I'm assuming it's not scraping anything else on the bike, of course.
