Agreed. The fact that some data is not on par with current Google offering doesn't make the product a bad one. Data issues can be quickly solved, specially when there are so many users to report problems.
For a maps application, the best report is just the location of the affected user. Any lookup on existing maps for that location will show what the problem is.
