While testing the upstream changes, entities defined in entities.include were skipped. I noticed shouldGenerate for entities option doesn't look right. I suppose it should have checked options.entities.include instead of options.path.include in Generator+Schemas.swift.

You can test it with any configurations that have entities.include. I believe entities defined in entities.include should not be skipped.

entities:
  isGeneratingStructs: true
  # Wanted to try this option!
  isGeneratingMutableStructProperties: false

  include:
