Refinery has changed quite a bit since its early days, and it's carrying around both tech debt in its code and configuration debt in the form of:

• Complex, badly organized, and badly named configuration values
• TOML-based configuration
• Defaults that are no longer ideal
• Tech debt in the code (older code that's only needed for backwards compatibility, some old libraries)

Cleaning this up requires breaking changes. We're going to release a 2.0 that also includes a configuration conversion tool so that switching to 2.0 will be relatively easy.
