Well, if the pipeline author is using try/catch to anticipate a
problem and work around it, it's going to be confusing to the user of
the pipeline if they get a bunch of error messages that aren't
relevant.

The error port effectively offers that sort of thing now. The question
is, how to bring those errors to the attention of the user in the case
where you don't want to abort the pipeline.
