Review comment:
This isn't actually true currently, non-existent lanes are currently treated
the same as not having a lane. I did this in #9407 because it seemed
friendlier, but an argument can probably made for making undefined lanes that
are present be treated as having 0 capacity which would make what you are
suggesting true.
