Brooks B17 without cutout: Anyone riding on it?

Today is new bike-for-touring day! My LBS gave me a great deal on a Brooks B17 and made a number of modifications to make this bike "just right" for me. They've been "my shop" for years and repaired my gravel bike every single time I've come home from our 4 and 5 day tours. But the B17 doesn't have a cutout... do all lady parts need the cutout or just some?
