I understand your concern, and actually there are two very different 
cases to distinguish:
1 - as indicated, "no pipeline matched request", i.e. the URL does not 
correspond to something handled by the sitemap
2 - a pipeline was partially built, but was not properly terminated with 
a serializer.

This only in that second case that your proposal applies, and this is a 
good idea.
