I am inclined to think in such a case it would be a redundant operation (that could be removed from the pipeline) and throwing exceptions should be for cases where something is known to blow up, like filling up an array from an infinite source.

There are a number of ways a pipeline can be constructed such that concatenation may not occur e.g.:
 
  stream.concat(anotherStream).limit(10)
  stream.concat(anotherStream).findFirst();
