I actually implemented this mod 2 months ago, but only released it yesterday after playing multiple hours with it, and optimizing it, and cleaning up a bit the code.

I also think the Circuit Assembler mod would be faster, as the recipe selection logic is handled by the game, instead of being handled by the mod.

I had a way to investigate the recipes, as this other mod do, but I removed the feature because it was too slow for a large game.

For completeness while we're listing variations of this idea, there's also https://mods.factorio.com/mods/justarandomgeek/dynamic-assembler - notably, I went a totally different direction with identifying recipes, to easily handle multiple-recipe items (in a consistent way across possibly different mod sets), at the cost of taking more effort to get the recipe id.

I don't think any of us have got this exactly right yet though, so the more the merrier!
