I'm unconvinced. Recursive queries have WITH at the front, not the
back, so the parsing issues are entirely different.
If we do find that, we can easily adjust this code to simplify the
filter function at that time. But I don't agree with reserving words
just because we might need them for patches that don't exist yet.
