I have no plans to change this for the basic machines. When I look into the mod configuration menu I might think about making it an option, but I'm trying to avoid the proliferation of inventory clutter, without also requiring a configuration step every time a machine is placed.
I mentioned it in another reply, but just in case: The mod portal doesn't give notifications to mod creators, so it's really inconvenient. If you want to continue discussing your concerns with the mod GitHub would be much better for me.
