The quality in the Irish lines has gotten better and better, the overly shy dogs of the past are no longer commonly seen. The long and low dogs are fewer now, bites and coats are now a lot more consistent. The movement to show them without a Terrier outline must be haunting Maureen Holmes in her grave. This is a trimmed breed.
Breeders are divided too much around the world. An Irish coated Wheaten is still at a significant disadvantage in the ring in North America, and in UK. This divide between the people who favour a heavy coat and those that favour an Irish coat has held the breed back.
