Sorry, I've must missed the two pings and noticed the problem only now while
housekeeping.
There is no easy way to peek cfglayout about what decisions it will do in
future, so there is no easy
way to decide whether to duplicate or not. I am not sure if this is important
enought, but if we really care,
we might consider if-conversion to do the duplication itself for really small
blocks.
