I don't think there is a particular reason, except that it has historically
evolved that way.

I agree that this could be useful.
What's important is that when you write
patch { image = "test.png" }
and test.png doesn't exist, that shouldn't cause the whole node loading
operation to fail, but load the "question mark" image instead and print a
warning. It seems to me that this could still be achieved with a getimage()
that uses standard Lua error handling, so I currently see no reason not to
change it.
