Well, consider it as an early "quality control alarm". :) If XEP has
built a PDF, is the PDF correct? Maybe, maybe not. If you haven't
looked at the (error?) messages, you can't tell.

The only way to tell is to browse through your 600 or so pages to
find the missing images. Not very nice.

The question is, should XEP abort the rendering process if it can't
find an image. Well, probably the FO spec gives you some freedom in
this regard. I would propose to make it either an option in the
configuration or in the command line. 

With such a configuration method, people can switch the behaviour: when
they are writing their documents, missing images are not very serious
as they will be added later. However, if they create the final
document, any missing pieces should are fatal and so should be any
error messages (which means, abort).

That would make such an error obvious and you won't deliver broken PDFs
anymore.
