How is that expectation established? It's not clear to me yet that this
isn't a documentation bug. It's also likely that current master will
not produce an error but the output might not be what is "expected". So
we need to nail down the expectations and the reasons for it, see
whether this restricts the possible forms of valid output or rather
"just" requires a certain structure to the input, something which could
be addressed using documentation.
