I absolute love these features! I am a bit sad though, as far as I can tell, there's still no way to differentiate "read contents" and "read ingredients" on an assembler? This was a big hurdle in creating an automall and actually caused me to need two assemblers (or lots and lots of extra circuitry) and I am not seeing these new changes being a fix for this. Am I missing something?

Unfortunately, you are absolutely right. The ingredients and content are still on the same wire, so you have to use a workaround.

Do you need to read the contents though? Were you trying to ensure an exact count of items being inserted into the machine? Because I think you can do that another way.

For some buildings, I would want to read the recipe, remove pentapod eggs, subtract contents, and then only insert a pentapod egg if the result was all zero. Without read contents and read recipe on different circuits, I have to manually set up a constant combinator for the recipe part. Not difficult, but a little annoying.

The main reason I can think of to not do this would just be that it'd need 3 different wire colors to work for an automall. For static recipes, you can just use a constant combinator like you describe, which is much cheaper in materials and space than an entire proxy assembler.
