I have a lot of old LV and MV machines from the beginning of automation. And only a few of them are needed for mid-game.
Currently, I use Deconstruction Table to recycle the parts of those machines. But this is definitely too op to get all items back.

So I would suggest adding "disassembling" recipes to simply recycle the machines into some useful resources, not the parts, only the resources. This can be referred to GT5 where we use arc furnace to smelt machines into ingots.
