Another good example of why you don't want this restriction
to just be "preceding siblings" is for the case of program-generated
pipelines.  In that case, there may very-well be a huge overhead
for determining "before" in the flow of components.

It just isn't necessary that the pipeline compiler enforce such a
rule because it doesn't need it.

I can only see this as being useful if it prevents the user from
doing "bad things".  While a user could write a pathological pipeline
in complete reverse order, I doubt that would happen.  The more likely
situation is where they insert an addition step out of order because
they are testing or quickly "fixing" the pipeline.
