Agreed ... except that 30 seconds later as cloud formations change, or 10 minutes later (in the golden hours especially) as the sun position changes or when you move your camera/subject/lighting orientation, it is no longer valid to the same degree of accuracy. If I can get my neutrals, neutral (when that's my goal), the difference between a full blown color checker vs. white/gray/black reference likely falls within the limits of personal preference anyway.

If your lighting and orientation are stable, then a color checker holds more validity as a reference. But, if you are "on the move" ... or your lighting is ... it's accuracy may / may not hold to the degree it technically offers (i.e. micrometer vs. yardstick) as it does in the studio where your lighting is stable. Thus, you'd need to reshoot a new reference more than just the once to ensure its continued accuracy relevance.
