Suggestion to add a 3x3 variant, which acts as an early recycler available right after quality 1.
Of course it should have worse stats for example 1/8 return? and no modules allowed? That could help with some early upstream quality setups.

I appreciate the concept, but I like that the crushers all have the same design language and the same factory role, adding one that handles recycling instead would be confusing. This could be valuable as a separate mod, and some situations combined with CI e.g. Muluna would benefit from having an early way to void resources, but I personally won't plan to implement this as-is.
