If you're going to "fix" wrinkles, then I reckon that you should do
"dents" as well.

There seem to be four groups of patterns to consider:-

Granite: Considerably different in a way that visibly alters existing
textures.

Dents and Wrinkles: Considerably different, but since they're mainly
used for normals the effect is far less noticeable.

Bozo and Bumps: Considerably different, but the point of the new noise
generators was to fix the existing plateaux problem with these patterns.

Everything else: Not affected.
