Works on a ghost of a crafting machine. Not sure if it is intentional or not (there is no other obvious way to check the recipe on a ghost), but it works. get_recipe() and previous_recipe don't do anything on a blueprint of a furnace, which makes sense.

Is this more of a comment? What do you think should be changed?

Doesn't CraftingMachine already imply that?

Not unless you know the LuaEntity inheritance tree. If you want to document how a LuaEntity can be two types at once, that would be great too!

You're right, probably best to be explicit. Fixed for the next release.

The whole 'Can only be used if' system is kind of bad in general though, it's due for a re-do at some point I feel like.

Ghosts can't craft and machines of them are an entity-ghost, so from a modder perspective, no. How I viewed it, hence the request. Similarly, seemingly far more important attributes, ghost_name, ghost_prototype, ghost_type, e.g. are separate. No ghost_get_recipe() or ghost_set_recipe()

Intuitively and without evidence and very personal opinion: No.
I generally assume that SomethingGhost behaves entirely different than the real thing.
